I have discovered that the best way to quit is to go cold-turkey. Every time I deliberate on something, chances are I find a way to hang on to it. I justify to myself the pros-of-the-con, and decide it's better retain than let-go and regret. Except it's really not. And the best thing to do if you're ever in this situation of permanent dithering is to just let go, close the chapter and forget. I've become amazingly good at quitting. Quitting habits, quitting places, quitting feelings and quitting people. Perhaps it's just the way Xeb-grows-up, but it gets so much easier to stop trying, let-go and move on.
Which is ultimately a good thing.
