You've obviously worked very hard to get to where you are but you also consider luck to be a very important part of your success. How much of success simply comes down to dumb luck?
Do you want a mathematical formula of how much dumb luck plays in success?
S = HW x P x DL/BD x ND
Where S = Success, HW = Hard Work, P = Persistence, DL = Dumb Luck, BS = Bull Shit, ND = Natural Disasters.
What I try to tell students, is that you can't expect anyone to do it for you. And if you don't try, it will never happen. Also be careful what you wish for, because you may just get it. And then you will have to find something else to bitch about.
