today is digital era, we have computer and smartphone.
for me the best way to manage our money is using our smartphone/computer, to write any transaction, invest, saving, buying a needs, having fun etc.
so we will know our saving, our investing etc. and we can manage "the best proportion of our needs"
Perhaps listing or writing down everything in journal or record is the most common way that we all know to manage finances and budget... Aside from that dividing your money and setting up which one should be on the priority and which one can be written on the next months budget is also good way of managing your budget... I my self is doing that, I adjust everything, I prioritize food, it has the largest share in my budget and the rest, it depends, like the bills, I put extra allowance on it and I based my budget on it on the last bill that I pay and just put extra so your money for it won't fall short...
