I Regret Quitting Astrophysics
Let me just say to all those out there who have left academia and went into industry: academia would be happy to have you back!I went into "academia" (or close to it), doing software engineering for a telescope being built.  Astronomers are a great little community out there, and they really need help writing code.  A lot of them aren't familiar or have experience with best industry practices that could save them so much time/money/heartache.Bunches of projects are hiring, and if you have creds, and industry experience, that will only increase your value.  I'm sure you could find a job at any of the wonderful facilities wherever you want to be around the world!Sometimes you have to look at the grass from the other side to realize it's greener, and that's fine.  Some day I may go back to industry and get paid again.  But it's all good fun anyway.
