Only I want to add that "to make a particular amount of money" with gambling is impossible so when this thought comes to your head you should know that you are probably making the wrong plans which might be the reason you lost all you have. So if you want "to make a particular amount of money" you better not even start.
This is very true, this kinda of mentality can be harmful. Go into it expecting to lose a little and just have fun, that way you'll never get suckered into chasing wins all the time.
