Hello!
Recently I have met different people who work with variable income (one month they can earn a lot and others not), the first one could save for a couple of months in which he would not receive any income. The second one simply could not save.
For both cases it is important that you know the fixed expenses such as; the mortgage, rent, what you spend in the market, in services (energy, water, internet, cell phone plan), installments of your credit cards, installments of any credit you have, etc. and the variables, even if it is an estimate of what things you would have to pay in the following days or months, for example, the doctor, an un-pinchada, buy double of an input that you usually buy (for this is important to have an estimate of how much is the maximum I need to provide in case I am asked for the maximum and of course who can provide me and what margin I would have to pay ...). but be careful, if you are careless with your suppliers and with your credits, prefer to look at how much you could assume of the order, and where they can provide you the rest of the order with a time and quality equal or better than yours.), buy clothes for a surprise event or an unforeseen expense, the arrival of a family member, etc. If you have the knowledge of these expenses the only thing left is to make a budget of how much you spend per month and save the remainder of your income each month, and the months that you earn little you will have to adjust the month without leaving anything out, eye ... do not be so relaxed with what you save monthly, it is true that you deserve prizes or that sometimes it seems that you can spend a little more, but please avoid it, set a goal of at least save for six months of expenses ... you will thank you.
Try to have willpower and make those around you understand that not every month will be so plentiful and you have to be careful with your tastes.
