How to change amtrak reservations
Change your ticket delivery method.
You can choose to have your tickets sent by mail or arrange to have them ready for pick-up at an amtrak kiosk, amtrak station, or amtrak vending machine.
Modify the times or dates of your reservation based on your new traveling plans.
OPTIONS:
- You should change your ticket delivery method weekly by changing your dates from 7 to 7 a.m. or bi-weekly by changing your dates from 4 a.m.
- You may change your schedule on the amtrak website to allow it to have certain times and date changing arrangements as well. For example, if you're going to amtrak this weekend, don't be surprised if your first couple of stops are extremely late.
- You have your departure time stamped and your travel dates during the day. You can cancel last-minute reservations that are later than the dates on your calendar.
- There are no penalty fees for changing a reservation. You may be required to pay the difference in cost if your new, updated ticket has a higher rate.

OUT: There are no penalty fees for changing a reservation. You may be required to pay the difference in cost if your new, updated ticket has a higher rate.

How to make a millipede habitat
Select the right size container.
A glass or plexiglas aquarium is ideal for housing millipedes. You can find one of these in a pet store.
OPTIONS:
- A 3-gallon (3.8 l) aquarium is a good size tank to make. It is best for 6-10 millipedes, a larger tank 6-10 millipedes, a larger tank 13-20 millipedes and a smaller tank 10-15 millipedes.
- That being said, all millipedes grown in captivity should be at least one meter in length. They should have a clean surface, such as a glass or plexiglas tank.
- The container should also be wide enough so that your millipede can hop into it comfortably without getting injured. Choose one that has sides that are equal in diameter to one inch (2.5 cm) thick.
- Such a tank will allow you to easily observe the millipedes and control the lighting. Plexiglas (hardened transparent plastic) will be lighter in weight, so this may be the best choice if you plan to take your millipedes along with you now and then.

OUT: Such a tank will allow you to easily observe the millipedes and control the lighting. Plexiglas (hardened transparent plastic) will be lighter in weight, so this may be the best choice if you plan to take your millipedes along with you now and then.

How to live in the moment
Start small.
While you might be tempted to completely overhaul your lifestyle, it is not necessary to make big changes to start living in the moment. Start by incorporating new habits one at a time.
OPTIONS:
- For example, going to the movies, going to the mall, going out to eat, or visiting museums will take away the focus on space. If you continue to give up your habits, you will take yourself and your surroundings to the next level.
- To continue living in the moment, prioritize personal and social values over financial values. For example, it might be unreasonable to expect to get rid of all clutter in your home while watching a baseball game or getting completely relaxed on a treadmill.
- Once you feel like you have mastered a habit, add something else. For example, instead of trying to meditate for 20 minutes per day right away, start by trying to meditate for three minutes per day.
- To make life easier and more comfortable, every move gets rotated at least once every year. Incorporate a new skill set into each move.

OUT:
Once you feel like you have mastered a habit, add something else. For example, instead of trying to meditate for 20 minutes per day right away, start by trying to meditate for three minutes per day.
