Definitely yes. What usually happens is that you have a job with which you cover expenses, or maybe you save a little and then you get a side job or two. With those side jobs you can save and invest a lot more, even increasing your spending level.
When someone wants to progress economically, the first thing they think about is saving, increasing income (while keeping expenses under control) is much better.
If you work and feel enough then you will not be interested in looking for a side job/business, but I suggest looking for multiple sources of income, the future economy will be difficult to predict and according to expert estimates that economic recessions will occur frequently, of course a side job/ business depends on our time and ability, we can be helped if we have a side job/business.
Actually not really because in reality many people are already rich but they still have a side business,
I think it's important to have more than one source of income, especially since we never know what the future will be like,
but it all depends on each individual's decision because everyone has their own decision.
Exactly, I will not tire of repeating it, rich people have several sources of income. Having only one is too risky.
It never hurts to have income from several sources, although there is usually one that accounts for 80% or more of income.
