Just do the thing. You know what it is. It's going to take like, what? One hour? At most? Just do it. It'll be easier to do other things after that, so just stop avoiding it. Don't you throw a pity party, it's time to do the thing. If you have to, put on your hat. Make that hat your working hat. Nothing can deter you from doing it when you have the hat because you're in uniform now. Sit up straight, respect your uniform, you're working on the thing now.

This does just sound like a jumbled mess because it's so late, but I think past me would get the point because yes, I'm far too motivated by what clothes I'm wearing.
