Most important advice is to lower expectation from gambling. Dont be on a hype thinking that right now you are the chose one who will start gambling and win jackpot. Instead, better prepare mentally that you are going to lose first money, lose it quick, lose it without fully realizing what is going on. Even be ready that second and third deposit also probably will be lost. Focus at first on gambling is where you spend money in exchange for time. Pay for experience if it is to say. After some time, only they understanding what to expect and where to aim at will come.
