That is a pretty good advise and I would recommend anybody to follow it that wants to save longterm. If we treat saving as a fixed expenditure like rent, food costs and other expenses, it becomes much easier to take the money away at the start of the month. In case we want to invest our savings in stocks or cryoto currencies it would make sense to automate the process, so that we have less work and don't need to think about. Depending on the country you live in there can be tax advantages for saving also. For example, in my country we can have private retirement funds that are subsidesed by the government and the employers. The money is taken directly from the monthly salary and we don't have to pay taxes on it, it also lowers my overall income and taxes. Additional I get benefits from my company that matches my contribution. The only problem is that I don't have any access to that money until I retire.
