No se de que hablas, aqui en reddit puro macho alfa que gana 250,000 pesos al mes. Mínimo 30,000 si eres pobre.
Edit: Ya en serio, aprende a administrar tu dinero, si tienes android descargate una app como AZV Money para crear presupuestos y controlar tus gastos.
App básica muy útil, bonita y barata (Gratis): Money Pro
Cuenta de débito muy útil, bonita y barata ($200.00): Cuenta Express Bancomer (Limite $16,045.65 mensuales)
For android I used this one: https://play.google.com/store/apps/details?id=com.azv.money&hl=en
However, since I changed to iphone now I have been using this one: https://wiz.money
To be honest i like Money Manager Pro but the downside is that they dont do ios. It is very simple and clean. I used it for over 3 years. However, when I switched to iphone I also started holding different currencies and stocks. Money Wiz is better, although I still prefer reporting of Money Manager Pro.
Both are free, although for moneywiz you have to pay if you want to sync between devices. Let me know if you want any more info. I am a student too, so I totally understand about the non regular income.
Money Pro is the best I've seen. https://play.google.com/store/apps/details?id=com.azv.money
