1. Are you interested in improving your current situation by starting a new life habit? 
2. How long does it take to form a life habit? 
3. Why are you looking to change the direction of your life? 

These are all interesting questions.

Personally I’m usually resistant to placing a time limit on self-improvement. In other words, if I’m going to do something to improve my life, or make my life better as you put it, then I’m going to automatically work to put that behavior into practice until I can master that behavior.
