Do something that matters
It is my assumption that everyone wants to do something that matters. I'm far from positive about this, but it just makes sense to me. The opposite is people just want to feel like failures much of the time - and I just can't see anyone wanting that. So then the questions are these:
1) What is it that matters?
2) Can I do something that matters here or do I need to go somewhere else to do it?
The answers (as I see them) are:
1) What do you have a passion about? I'll bet others do to AND would benefit from your passion, understanding and expertise. Share it and watch what happens.
2) Yes. There is not a perfect place or ideal time. Certainly timing can be important, but if you wait to find the right mix of whatever you are waiting for - you will never even start.
Good luck. Let me know how it goes for you!
