Here is thing I learned when I was 29, which I now give away for free:
If you want to do a thing, do it now, or as soon as feasible. Because there might not be a later.
But to succeed at a thing–a job, a relationship–in the long term, the thing is: You Must Commit, even though commitment is scary. And commitment is scary because once you’re in you’re in. It’s not bobbing around close to the shore, paddling with your feet. It’s both feet and swimming as hard as you can out where the rip currents and the sharks are, where the water turns blue.
— Elizabeth Bear, everybody’s scared of things that they don’t understand and all the living they don’t do.
