Let's say when gambling, you follow a specific pattern. Let us use lottery for example. You bet on the same specific set of numbers. What would be more regrettable? Betting on the same set of numbers for the rest of your life and not winning or... changing up the set you bet on only for your old set to win?
Basically, would you rather bet on the same thing again and again then regret not exploring more or explore different kinds of bets then miss out on a win?
It's highly possible that either one of these two will happen, luck still plays a major role here, the truth about gambling is something will always lead to your failure, and you will be left with reasons why you never win.
We always find something to blame in the end when things don't go our ways, this is us humans, I do this too but in gambling it's a different story, because I know that gambling is sick.
Everything is meant to go wrong in gambling, and that one time that things go your way is pure luck, blessed are those who accept this for they will be able to manage their interaction with gambling the right way.
