I think it is obvious that when you make enough profit from it just once, rest is quite easy as well. I mean if you joined the market when it is bear, and wait until it is bull even just once, you made a good profit, and then sell it, wait for a huge crash, wait for it to drop 70%+ and then buy again, and sell again when you make 5x or more profit, even x10, and then repeat that many times over.
That's how wealth happens, all you have to do is the first bear market entry and bull market exit, if you could do that then the rest is incredibly easy and shouldn't be an issue for you at all. I need to explain how hard that is though, going in at the right time and going out at the right time, have to realize that's a tough job.
Everything seems pretty simple to understand, but it's not so easy to implement. And it will also be quite difficult, because if we need several cycles to reach a good fortune, then it will take us a long time, because each cycle will last about 5 years.
But if we understand how it works and how long it will take us to achieve, then we can roughly calculate when we can achieve financial independence. And you are right that it is very important to determine the entry point and the exit point, these are very important moments.
