What can I learn?

It’s the way I’m trying to look at current situations and opportunities. What will I learn if I decide to complete this project, hobby, job, book, or goal? I’m a person who is constantly accepting new opportunities and challenges. Only to have my time constraints affect the final outcome. What can I learn? Will be the question I ask myself each time I decide to commit. I’m hoping it gives me the time to think about the other questions I should also consider before committing, like the amount of time it will take to complete, what can I do with it, what is the reward, how much will it cost, what kind of help or tools will I need, who can assist / teach me or how my family will be affected.
