If there’s something you need to do but you don’t really want to (but you need to), set aside time to do it at some point during your day and then forget about it.
Don’t forget about it completely! I mean, forget about it until that time comes up.
Let’s say you’ve got to mow the lawn, and you just really dread it. Well, instead of thinking all day about how you’ve got to mow the lawn but you really don’t want to (but you need to)–thereby tainting every joyful moment you have throughout the day with that “Yeah, but I’ve still got that lawn thing…” feeling–just pick a time that you’re going to do it, set an alarm to remind you, and then try your best to get it out of your mind.
Every time the thought occurs to you, just happily wave it away like Tony Stark dismissing a reporter. Yeah, I know about that. It’ll get taken care of. Don’t bother me right now.
When when your alarm goes off, do the thing, get it done, and get right back to whatever it was you were doing before.
It’s sort of like compartmentalizing, which, as a concept, kind of gets a bad rap. We should embrace our mind’s ability to cordon things off and shut them out when we don’t need them. It’s quite a useful adaptation. Especially when you don’t want to mow the lawn (but you need to).
