Currently I am still single and I have a job, at first I didn't think about anything except what I needed and wanted. When I got my salary then I would fulfill what I wanted like gambling, when I first got to know gambling I was very obsessed with being able to get a big win in other words I always wanted to gamble sometimes to the point of spending all the salary I got from work. But over time I realized that gambling is not something that should be done continuously because it will only make us lose money. From here I started to reduce my desire to gamble and divide my finances evenly to pay the bills that are currently my own responsibility.
Well that is something that should always be seen in the best light, when we go through tough experiences that make us give it all we have, then we learn, when we are single few things interest us, and we can do and undo, but there are always responsibilities that should not be avoided, just as you say, it is very difficult when you have a family with children where you are the head of the family, money is already a more delicate thing to manage, then like that you can't fail at anything, obviously the single life is unique, responsibilities are less but even so there should be and never neglect responsibility.
