There is some measure of not making the same mistakes twice, to be fair. Your first few weeks as a brand new founder you might accidentally find yourself debating which bank to use for days or a week; the second time you'll never make that mistake because it will have been entirely inconsequential the first time.

Basically, it gives you the opportunity to do less "work that looks like work" because you did that before and was ineffective. You'll find plenty of other ways to do that, but at least you've narrowed the scope of stupid things to do a little bit. :)
