Think of following before you start your next significant project.
Will you enjoy it?
Will it allow you to meet interesting people?
Will it expose you to interesting ideas?
Will it stretch you and help you grow?
Can it make you money, or get you to meet new friends if that is what you’re after?
What if it didn’t make money? Will you still pursue it for a year or longer?
Is it fulfilling?
Will it serve the lifestyle you want for yourself?
Once you have thought well about these and your gut tells you to go for it, then go for it.
