To aid with your goals and create a good habit or healthy lifestyle, I recommend creating a journal. Writing down what you do each day working toward your goal provides conscious thought about doing it. Eventually, the actions and journaling will become an established habit.
As a common example (weight loss):
Each day, in a notebook, livejournal, etc., list what you ate for the day. Include calories, fat, protein, carbohydrates, fiber, or whatever you feel are relative to your goals. List your totals.
A good source for foods you are unsure of is www.nutritiondata.com
Below your food, list all exercise completed for the day. If you'd like, list an estimate of the calories burned.
