Don't ever look backwards, it's a waste of time.

Learn the lessons of your misses and take them with you.

If you were recruited multiple times to join FB you are going to continue to have great opportunities.

If you're inspired by the idea of valuable stock go build a list of what you consider to be the top 5 start-ups with traction.

Then find a way to engage them.

Even if you missed on FB, you can still catch the crazy-money boomerang and pull out MILLIONS in the next 3 - 5 years.

Heck, write a blog post lamenting your FB miss and weave it to talk about your credentials.
