I usually do a form of cost-benefit analysis before making any decisions.

1. Does the project bring me joy?
2. Is it connected with my larger vision and mission?
3. Is it aligned with my values -- the project AND how I operate it?
4. Is it aligned with my positioning?
5. Do I already have paid customers who still require fulfillment?
6. Is this taking out more energy than it's fueling me?
7. Am I resentful about the project?
8. Do I dread sitting and working on it?
9. Is it taking away time and energy from other projects that are more lucrative, joyful, or aligned?
10. Am I getting out of it what I set out to? (If I started for business, am I making a profit? If I set out for pleasure, do I find pleasure?)
