If you want to control your hand, you can pay your salary every month, invest in a fund (if you make a fixed investment, you can spread the risk equally, and it is best to deposit it in the bank, and the rest or zero one), or you can deposit zero one (the current interest rate is 1.9). Do not use it. Well, you can still use it, so I still think it's more convenient to make a fixed investment. Anyway, I am also like this: daily expenses 1/3, fixed investment 1/3, savings 1/3 for my parents and myself. )
Look at your own shark bookkeeping book. There are categories and details in it, and you can see which ones you shouldn't buy after "passionate consumption". Anyway, I insist on chopping hands and have 7 or 8 mobile phone cases; Soymilk machine or something is useless after being bought and used once or twice. ...
Take your time, you will save money, and you must have a sense of financial management. hahaha
