Set a goal. This gives you meaning.
The goal should be realistic, achievable, and honest, not based on hyperbole, fantasy.
Your goal should be personal, not what others do, or think you should do, or think is worth doing and/or not doing.
Prepare for a degree of disappointment because no matter what the real and the ideal are never in sync. The degree your goals are realistic and honest determines the degree of disappointment.
Then settle for the outcome, and move on.
