Well spoken mate!
But spending less compared to what you earn is not the ultimate way for becoming financial stable, the only way to be financially buoyant is making your money work for you.
When you receive salary try as much as you can to set a side amount of money for investment and look for a lucrative investment and put in your money.
Your suggestion is quite reasonable regarding how to stabilize finances in this life, but if we look at the investments that can be made by people who have regular salaries through their jobs, of course everyone can also use the money in a business that can generate more money in a short time, although savings through investments such as Bitcoin also need to be considered very wisely because it is also a very good thing for everyone in the present and in the future.
Because to make finances run more stable in ourselves, of course we must have several sources of income so that investments can run routinely without obstacles while trying through certain businesses and also working as usual with a regular salary every month.
