In the allotted time, you need to have time to realize the potential inherent in you. Many do not have time. They are on a different path. They can choose one path, be disappointed and prefer another. But even then, the choice is not the same. You should not look at the horizon of opportunities, wanting to catch luck by the tail. You need to act for sure, in accordance only with your own principles and beliefs. Descendants will say how justified it was to live. This is how it happens - as Mikhail Bulgakov is an example.
