I agree that this is a significantly different proposal than the original idea. It's a combination of the original idea with another idea in a munchkin-like fashion with a different result, but one that is potentially better/more powerful/has higher XP (though it's not guaranteed, of course). I wouldn't call your points problems though, just differences.
By the way, there are ways of getting yourself to put in the necessary work (i.e., overcoming akrasia), and this community is great at coming up with a lot of them. Do you think that if you had $10,000 (to throw out a number) to spend on improving yourself and you decided that akrasia was your weakest link, you could come up with some ideas/systems which would make a significant difference? Is that likely to be worth $10,000?
Is that likely to be worth $10,000?
Is it likely to be worth more than the other possible uses for $10k? Your phrase "to spend on improving yourself" already assumes that this is the best use of the money.
Additionally, I think you missed the point of my objection "You have to put in work". If you successfully spend $X on reducing akrasia, then your work for the rest of your life will be more efficient; great. But you still have to work for the rest of your life. If you invest $X in income-generating capital, then you have income for ...
Thus spake Eliezer:
It seems that many here might have outlandish ideas for ways of improving our lives. For instance, a recent post advocated installing really bright lights as a way to boost alertness and productivity. We should not adopt such hacks into our dogma until we're pretty sure they work; however, one way of knowing whether a crazy idea works is to try implementing it, and you may have more ideas than you're planning to implement.
So: please post all such lifehack ideas! Even if you haven't tried them, even if they seem unlikely to work. Post them separately, unless some other way would be more appropriate. If you've tried some idea and it hasn't worked, it would be useful to post that too.
