Being patient and consistently involved in healthy gambling habits will surely make you a successful gambler.
Do you mean a gambler should be successful in gambling? It is good to be patient while gambling and it is good to also follow the rules for you not to be addicted or lose too much money, but gambling is not where we should think about success.
Actually, success has many meanings, but if what is meant is success in generating profits to enrich oneself then that is wrong because the definition of successful gamblers are those who can control themselves and their finances in gambling.
Most gamblers are controlled by their gambling activities so they forget control and end up becoming gambling addicts.
Personally, I limit my bets to no more than 10 percent of my bankroll per day, I stop once that limit is reached.
My gambling budget is 5% weekly. From the 100% I earn weekly, I used 5% or less to gamble if I have time to.
That is pretty good financial limit because you can use your money as well as possible and manage your income and gambling expenses wisely, it is very rare for gambler to have a patent limit like you for gambling.
I myself have at least limit of 10% to 30% for now because I myself have experienced many bad experiences from gambling which caused financial problems a little and I don't want to repeat this.
