If there was a giant meteor hurtling at the earth, and the end was near, what would you regret having not done?

I’ll go first:

I had this thought a few years ago, and for me it was my desire to write and perform music. Yes, I wanted to be a “rock star” in a way. I had a bit of skill, and some song ideas, while at the same time the idea of putting my soul out in front of everyone scared the crap out of me. I have major stage fright.

So.. being the nerdy control freak that I am, I started my own Open Mic night at a friend’s bar. For many weeks I drove all of my audio gear there, I hosted lots of amazing people.. and eventually I performed. I played and sang my three songs. People loved it, but all the while my lips turned blue due to lack of normal breathing, and I certainly never made eye contact with the crowd more than once. That night I felt like I accomplished my goal, and learned my limits. Mission accomplished, I am now ready for the theoretical end.

Would you have any regrets in a similar thought experiment?
