you are right. Of getting used to it from a young age to be able to set aside whatever you get to save is the best and very good action to do, even though usually you will always be tempted by the desire to satisfy your lust when you are young. But because of the high awareness of saving, with the aim of the future, especially when you no longer have a permanent job. So that what you have saved can be used for old age or if you want to create another business from some of your savings, this is also possible. No one knows that later when you don't work you can still do other things, of course it would be better, but if they don't have them, savings will be the saving grace.
In my opinion, almost all parents teach their children to save from an early age, because this really needs to be paid attention to, because when we grow up we have to be able to manage our finances well, including having a job that makes money and we ourselves have to be able to manage it well. Having the habit of saving from an early age is certainly good for the future, because if we can't manage our finances well, in my opinion it will cause us difficulties in adulthood. I have seen many young people who can be said to be adults and already have a clear job with an income, but they often have problems with their income always running out somewhere, so it makes things difficult for them, and I think that's because they don't have money management. What's good is that young people nowadays usually only think about a luxurious lifestyle which can be said to be only temporary and that means they always put aside their own needs.
I agree with you, if you already have a steady income and are confident that you can have your own business then there is no harm in that, it is a good thing to try, even if there is failure but don't be discouraged, because to be able to reach the point of success or financial freedom of course there must be a struggle. and just be sure that your efforts will not betray the results.
