What is your reason to gamble? Fun or profit?
It is only fun for me if there is a profit. And the profit is never automatic. It always requires some discipline, observation, patience, aggression, finesse, and learning.
All the requirements you have mentioned are only for gaining profits from gambling. I believe they are not required if you are going gambling for the purpose of making fun out of it.
Yes, even without making profit you can enjoy with gambling. The gambling is fun is not hidden under profits. But it is highly up to the gambler's mentality like what he expects from gambling.
