How to keep your pond clean
Clean your pump's filters out regularly.
Most filters require cleaning once each week. Usually, cleaning is a simple matter of removing the filter, spraying it down with a hose, and replacing it.
OPTIONS:
- If you notice any signs of issues, like improper cleanings, loss of power, or blockage with the water meter, clean it out. You can purchase automatic filter cleansers at your local hardware store or online.
- However, you should always follow the manufacturer's instructions when deciding how and how often to clean your filter. If you notice your pump leaking or struggling noisily, you probably need to clean it.
- If you do not clean the filter regularly, you may accidentally cause an economic strain on your water supply, which can lead to major health problems down the road. Remove water from your pump after it stops running and replace with fresh water if it is dirty.
- Sometimes, cleaning due to an accident can only get you so far. Decide on a cleaning schedule that works for you and your pond.

How to write an apology letter
State what your letter is about.
It's a good idea to begin by letting them know that this letter is an apology. This will give them the chance to put themselves, emotionally, in the right place to read the rest of your letter.

OPTIONS:
- You don't want them to be confused about why you're writing or what you're going to say. Say something like: " i wanted to write you a letter to apologize for what i did ".
- This may be helpful if you are writing about a lonely customer or a breakup. Explaining why you are apologizing may be easier if you can make sure the person understands what you mean.
- Do not include a sentence about what you want out of an apology letter. This will detract from their motivation, and may even cause them to rewrite a more thoughtful letter.
- This will show them that you are in control. Here's why you might begin your letter with " i'm writing to apologize for not calling during business hours.

You don't want them to be confused about why you're writing or what you're going to say. Say something like: " i wanted to write you a letter to apologize for what i did ".

How to befriend dogs
Make sure the dog is friendly.
When approaching a strange dog, be particularly aware of its body language. If an owner is present, ask the owner if the dog is friendly.
OPTIONS:
- Make sure the dog wants to be petted. You can easily alienate a dog by approaching one that is nervous or agitated.
- If a dog seems hesitant to meet you or extends its hand to you, it's the opposite of friendly. Avoid approaching a dog by walking near it and stopping so that the dog can see you.
- Usually, a dog looks friendly when greeting a stranger but when the dog is not, try something more benign. Some common signs of friendliness on dogs are legs waving, laughing, and shoulder-shaking.
- Common signs of friendly behavior are not always direct stares. If a stranger approaches the dog, its body language may indicate a definite dislike.

answer: Make sure the dog wants to be petted. You can easily alienate a dog by approaching one that is nervous or agitated.

How to retain knowledge
Use spaced repetition.
If you want to remember something, don't repeat it over and over to yourself-this is known as massed repetition. Instead, let some time elapse before you repeat it.

OPTIONS:
- To ensure you haven't depleted your memory beyond 20 minutes, try counting about ten (you really shouldn't) for no more than five minutes each day. When twenty minutes have passed, move on to the next thirty-five minutes.
- Ideally, you want to try to retrieve the information exactly at the moment when you were about to forget it. The difficulty of retrieving the information correlates to how strongly you will remember it.
- For example, if you are memorizing a presentation, pause and think " wow, i missed that presentation. Let's go back for it later " and no longer repeat it; this will still make it harder for you to remember information.
- This will help you retain the information all at once and can also make a much more significant impact on the learning process. Practise this practice the next day or every third day until you've become a better learner..

Next sentence: Ideally, you want to try to retrieve the information exactly at the moment when you were about to forget it. The difficulty of retrieving the information correlates to how strongly you will remember it.

context: How to build a model
Take your model kit out of the box and compare the pieces to the instructions to make sure you have everything needed.
Kits do (infrequently) come from the factory with missing or damaged parts. The time to return it to the store is before you begin assembling it!
Wash the parts.

OPTIONS:
- Take a sponge and press down on it to remove particles. Rinse any dirt off of the parts.
- Cut them out carefully, leaving a 1/4 " (0.6 mm) seam allowance on each piece of body. Preheat your oven to the mark 4 f (10 c).
- You will need soap, water, a cotton swab, a rubber band, two plastic parts, a small brush and a damp rag for cleaning. Prepare the kit with soapy water.
- Using an old toothbrush, some dish detergent and warm water, carefully wash the parts of the model while they are still on the parts trees. Rinse the parts thoroughly and allow to dry completely.

How to know if you're sleep deprived
Be aware of decreased cognitive function.
It's no surprise that a lack of sleep can cause irritability and changes in mood. You may actually develop a mood disorder if you're consistently sleep deprived.
OPTIONS:
- Disruptions in the sleep cycle have been strongly connected to depression and a reduced quality of life. You may also feel more anxious and lose your motivation to do simple everyday tasks.
- Don't be surprised, however, that you may not still be irritable after a long day. Another sign of possible sleep-related issues is the cognitive function (dyslexia), which is a sign that cognitive functioning is the result of a weakened receptor in your brain.
- If you experience major depressive symptoms that coincide with your sleep cycle, don't ignore them. Some people experience feelings of sleepiness or sadness even after poor sleep.
- You may begin feeling refreshed if a new setting or a new person seems to affect you physically or emotionally. Your physical appearance may change as you gain new skills or become more active.
A:
Disruptions in the sleep cycle have been strongly connected to depression and a reduced quality of life. You may also feel more anxious and lose your motivation to do simple everyday tasks.
