Pre App launch jitters...

I'm going into alpha/beta testing phase of my app. I'm pretty excited but also am kinda nervous.

Whenever you launch a product of any kind, it's human nature to second guess yourself and to ask "why am i doing this?" or "Will this work?". Or the big one, am i ready

Well you are never ready, it'll never be good enough, and you missed something. Big. Shit happens. Be a man and move on.

When you mess up your git pull

Remember this chunk of code:
sudo git reset --hard HEAD

Use that code snippet when you don't care about the changes on the local machine you are git pulling and your git pull request won't merge.
