In your thoughts, you need to be selective. Thoughts are powerful vehicles of attention. Only think positive thoughts about yourself and your endeavors, and think well of the endeavors of others.

Meditate. Look at the candle flame - or whatever object you have chosen to gaze upon - with intensity.

In my estimation it's silly to go out and spend your time aiding people if you don't have your own act together yet. So I'd rather you spend the time, get it right, and it'll all work out a lot better.
