I think is a bit of luck in things, however a lot of “luck” is being right place right time. But you have to put yourself in that place. Some examples of luck I’ve heard. People buy a unit thinking they were getting a single family. They bought expecting a single unit, come to find out it was zoned multi family, adding a 2000$ window makes a multi. I work with a guy who had bought mineral rights to his property(not luck) then had a massive oil pipe bust that no one knew about. Now what he collects in payments from oil company more than pays his mortgage.
We make some of our own luck. That said playing sports there is luck. A guy hitting a 3/4 shot in basketball who couldn’t hit a standard three point shot is luck. A Defensive back slipping at line of scrimmage and Wide Reciever catching a wide open pass is luck. Hitting the lottery is luck. Rich family members leaving some idiot offspring an inheritance is luck.
I will say this though most things are blessings and neither luck nor skill. I was blessed to be born in USA. I was blessed to be able to think somewhat logically. I am blessed to have pretty good health. These things are way beyond the scope of anything I could do. I can’t choose where I was born and raised, I didn’t choose to have good health it was given to me(yes I know lifestyle choice factor into health).
