You should probably read the Anti-Akrasia Tactics Review, if you haven't already. There's lots of useful stuff there, and if it works for you but you haven't read it...
You should totally go read it, implement it, and not come back to this thread until you've internalized your favorite tricks.
Feel free to discuss outcomes here.
Did anything work for you?
Is there anything that should be added?
Note: this is basically a "bump", but I suspect that it's a worthwhile reminder. Downvote me if I'm wrong.
P.S. I'd actually really enjoy feedback on this.
Of course, how hard it is depends whether you're in, say, Indonesia or Finland!

I stopped catching the colds that had plagued me all my life before that. I also feel an increase in willpower, but that could be imaginary, or due to something else.
