Self improvement can be simple!

Step 1: Make new self-improvement goals for this month.

Step 2: Do your best to achieve your goals.

Step 3: Next month report back on your progress as well as make new goals for the proceeding month.

Step 4: Become a more awesome person!

Factors for success for creating good goals:

Quantify your goals ("I want to lose 5lbs or 2% body fat" is a better goal than "I want to lose weight".)  Make goals that are realistic. Don't try to lose 50lbs in one month.  Make goals that are sufficiently challenging, push yourself.  Create a specific plan for reaching your goals.

Your goals can have to do with anything that you want to work on.

Good luck!
