How to lose before you know it

I joined a chess tournament on here, not really thinking about what I was getting into. It has me playing 18 online games at once, which at the time was more games than I had completed. I don't think I'll make it to the next round because most of the players in my group are ranked higher than me. Here's a game where I lost before I knew what hit me.

Lessons learned:

• Castling is important. Don't be overly picky about where!
• Develop pieces with a purpose, not just to get them out. Im I had kept my queen closer so it had been defending other pieces, things might have gone differently.
• When an opponent moves, pay attention not only to where that piece is going but where surrounding pieces are going.
