Hobby or Business
If you're like me, you have too many ideas, too many things you want to do, and too little time. One of the first things I decide when I have a new idea is whether it belongs in the “hobby” bucket or “business” bucket. Hobbies are allowed to cost money, businesses need to have a way to make money. Ideas can flow back and forth between the two, but it has to be a conscious decision.
Many software developers have the concept of a “side project”, but they never consciously decide if it is a hobby or a business. Many hope they can spin it into a business at some point, but they're working on it like it's a hobby, spending too much time tinkering with details that are unimportant if it's a business. This just results in frustration as you eventually close the door on yet another “side project” that never went anywhere.
