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.
If someone still single but he can have an income, he must not waste the money with preparation for his future. He will see that he can save some amount of money to run his plan step by step so he will have a better future. But many singe person can not understand this and tend to waste the money for himself without create a plan for his future. If we want to playing gambling, we must realize we need to have rules to control ourselves in gambling so we don't just use the money without saving for our future. We need to realize that our future will be important for us so when we are deeper in gambling, we will lose the opportunity to have a better life. I am sure that no one will want to get that so we must aware and start to prepare our future. That is why we must responsible with anything we want to do so we can achieve our goals without getting a problem and in this matter, we should stay away from gambling addiction.
