What to do?

I've been spending a lot of time thinking of ways to optimize the engine.  But I've also realized that I'm wasting time trying to optimize when I should be doing new development.  I'm missing out on creating the new technology to push The Render Engine over the top.  So, starting tonight I'm stopping my optimizations and going back to working on the new stuff.  Maybe it's silly, but I get caught up in trying to make everything perfect out of the gate.  So, back to the UI, tilemap renderer, multiplayer, and other things.  I'll be sure to record what I was working on so I can return to it, but for now it's back to the new tech.  =)
