Lazy to Successful overnight

I really don't think so. Turning from lazy to successful is pretty much like ANY other change in oneself that a person wants to incorporate.

Whenever a change happens in our lives, our mind needs time in order to adapt with the new situation. Earlier that person was lazy - that's just how his mindset was, of procrastinating, avoiding work, etc. There's no magic pill that he can take that'll turn him into a devoted workaholic - there simply isn't (well, not right now. It's interesting to think that Psychologists might develop a solution to that in a future far away from now, but anyway , at the present moment - I highly doubt it).

However, if some particular event happens that makes a lazy person feel VERY determined, even.. he might be able to work in a dedicated manner for a bit, but after few days again, he'll probably procrastinate some work here and there - means he hasn't fully gotten rid of his laziness, and completely getting rid of laziness DOES take some time. One has to constantly keep reminding themselves that they have to stop being lazy, and they have to DO something about it. It takes a lot of time and effort to reach the near-perfect stage.

Oh crap! That reminds me, I need to stop procrastinating and get to work. Blehh.

One more thing:

Interesting point of view. Here's what I think about it:

Creating a business is a lot different than changing your mindset. Going on a date is a lot different than changing your mindset, as well. Agreed - sense of entrepreneurship and being a lonely-kind person means their mindset is like that, but in your examples, you're considering a typical common man. If a person is a total loner, and decides to go on a date - yes, that's a change. Actually, I'd rather say it's the INITIATION of trying to change. OK, well, if a person is a total loner, and he decides to go on a date, he won't be confident in the beginning. It's not like he can turn himself into a guy who loves social gatherings, parties and dates overnight. If he's going on a date, he's simply beginning trying to change his mindset. And in this example (of laziness), we're considering a MAJOR change in the mindset - from a procrastinator to a person with no laziness and a hard-worker. If he's starting work, it's the first step to change. He isn't a completely different person right next morning.

Anyway, from your post, I can tell that your point of view is different. You're considering "change" in literal sense. Of course - going on a date means there's a "change" brought in his day. We're not talking about such changes in this thread, we're talking about changes of how one perceives things - how one's inner self thinks and acts.
