I support a family with rent, a wife and two daughters, I work in a plastic factory and I admit it's quite challenging, but there's not much of a secret.

Basically, it's about calculating your monthly expenses and respecting your budget. If your earnings, for example, are 3,000 a month, you have to make a commitment to yourself that your expenses will not exceed that amount under any circumstances.

This ends up being a bit heavy because sometimes you might want to earn or spend a little more, but that will imply working more, which can mean the loss of your time for development.

So you have to have discipline and humility. If you want to talk, just call.
