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"
Thats true, it is really the best way to manage the money if you keep jotting down the expenditures or the savings you are doing after getting your salary, and at the end of the month you should see what you did with the money and how much you have saved, and if there is something you see should not be done you should skip it next time.
Yeah having your own digital record really makes managing your money easier.
Though when I record my day to day expenses I write them down - pen and paper - then I'll just transfer to the computer.
