It's hard to change. Sure we talk about it, but we rarely do it, or we don't make it stick. We'll track the cigarettes we smoke and "try" to cut down – and ignore it when the number doesn't change for months. We try weight loss and organizational plans and all that and it doesn't work.
Yeah, you're probably nodding, if only in your own head.
Think of change as a skill as opposed to something you have to do.
You've probably had times people tell you to give up your fannish hobbies, your meekness, etc. Grow up, they'll say. Get a life,you'll be told. This is immature, you'll be informed in a snooty manner.
Forget that.
The problem for many people is NOT that their fannish hobbies and geeky interests are immature, or time-wasting, or whatever. The problem is people do NOT take them far enough.
