Pro gambling has very expensive overhead for Singaporean in Singapore. S$100 per entry. I like Tahoe and Genting, used to be there once every few months. No pro gambling am I, just have a budget to lose and target to win. Whichever side is hit first, that's it, game over.
I started with paying $100 per entry - both at RWS and MBS. Paid almost 2k from these per trip entrance fees. Meaning about 20 trips.
Once I realised I could chari makan in the casinos, I paid the 2k from my winnings. I still recall it was winnings of $1000 and $1100 or the other way round for two consecutive days.
You need capital, time, patience and most importantly, DISCIPLINE to make gambling as a profession. It can be done, trust me. Greed kills a gambler. That's why I emphasised discipline as THE most important trait.
Even though I am fully aware, at times I also cannot control. When lose, si pay tu lan, bet bigger. DON'T. I am still mastering the art of gambling.
