Article: It generally takes 21 days for an activity to become an ingrained habit. Make sure you consistently do your routine tasks every day for 3 weeks to get fully accustomed to your new routine. You will probably still form a habit after 21 days if you miss 1 day somewhere in those 3 weeks. However, if you find that you skip your routine on 2 or more days, consider redesigning your routine to make it easier for you to accomplish every day. Once you start doing the activities in your routine without thinking, then you've successfully formed a habit! You'll probably make a mistake or slip up in implementing your routine at some point. Instead of berating yourself, give yourself some leeway to accomplish only some or even none of your routine for that day, then set out to be successful the next day. For example, if part of your workout routine involves doing 40 pushups, don't beat yourself up if you only do 20 during 1 workout. Instead, recognize that you still accomplished part of what you set out to do and try to do better next time. Don't give up on your routine if you fail early on; it will get easier over time. At the end of each week, check in on your progress towards your goals and see whether your routine is helping you reach those goals. If it isn't, consider what aspects of your routine might need improvement. For example, if the purpose of your routine was to make you more productive in the mornings, look back over your week and see how many times you've arrived to work earlier or later than usual. If your routine has made you get to work earlier every day, that's a good sign that it's making you more productive in the mornings. For more long-term goals (e.g., losing weight), it might be better to check in with your routine at the end of each month. Once you've designed your routine and have had time to test out, don't be afraid to go back and make tweaks over time. Whether you want to add or subtract tasks or recalibrate your activities for a new goal, treat your routine as a fluid and ever-changing list. For example, if you find that your workout routine has gotten too easy, consider going back and adding more difficult exercises into the mix.

Simply double-click an Excel document to open it in Excel. Doing so will select it, allowing you to type into it. This command indicates that you want to multiply items together. This should be the cell at the top of the range of data. For example, you might type "A1" here. . The colon symbol (":") indicates to Excel that you want to multiply everything from the first cell through the next cell you enter. This cell must be in the same column or row as the first cell in the formula if you want to multiply all the cells from the first cell to this one. In the example, typing "A5" would set up the formula to multiply the contents of A1, A2, A3, A4, and A5 together. This last parenthesis closes the formula, and hitting enter runs the command and multiplies your range of cells together, displaying the result instantly in your selected cell. If you change the contents of a cell within the multiplication range, the value in your selected cell will also change.
