There are two types of luck, good and bad, and I don’t believe in either of them.
Luck assumes that the universe is working for or against you, and I don’t think the universe gives a shit one way or the other. You’re either prepared or you aren’t, and the rest is by chance.
And yes, there is a difference: luck is the idea that circumstances happen to you; chance is just what happens. It’s not egotistical, and it doesn’t allow the roles of victor or victim. Sometimes you benefit and sometimes you don’t, but it’s rarely ever about you. It just is what it is.
There’s a saying that God has a plan for us all, and I don’t not believe that, but I think our final hands are usually just Him showing mercy and dealing us breaks. There’s another saying that everything happens for a reason – I definitely don’t believe that, because too often it’s an excuse people use not to change.
They readily blame “God’s plan” for their shortcomings to stay subjective and trade lessons for self-given assurance that they were sidelined for a reason, when really, most of the time there is no reason. Unless the reason is that you suck.
If that’s the case, don’t baby yourself. Accept it and work to improve.
“Luck” is made. Not by the universe. By you.
