Here is my approach to goals.

1) Aim for no more than three at a time.
2) Share your goals with as few people as possible (this is scientifically proven to help)
3) Don't try to commit to goals for long periods of time, fixate on a management amount of time. (i.e. 2 weeks, 1 month, etc.)
4) Make sure your goals are realistic, and if you have anxiety problems then aim for smaller goals which are priorities.
5) Be compassionate to yourself, accept that you will fail and don't be afraid to try again.

Currently my goals are:
1) Meditate for 10+ Minutes Each Day
2) Exercise for 30 minutes Four Days a week.
3) Journal Every Night.

The trick is to build habits and then focus on new goals.
