The only thing you should be afraid of is losing control of yourself. As you are starting new, you need to start with having a budget and having a plan, which should also be included in your strategy, and try as much as you can to keep to that plan which you have initially set up. Don't allow anything to lead you to not keep to it, because when you lose control of how much you are supposed to be spending on gambling, it could lead to risking more than you can handle, which is what a gambler should not do.
Yeah, as a gambler you must have full control of yourself and avoid being to addictive so you won’t go on to gamble all your life saving. Talking about having proper budget, security and plan I think you should consider all of that before you even start the process of gambling because by proper planning you will be able to overcome your fear and lot more.
Self control is a very crucial part of succeeding in gambling because most people who lose everything in gambling don’t have self control and that is the reason why they go ahead to gamble all the have in something they should have controlled themselves on.
