Have you ever heard that phrase? That means you should put some money aside for savings, a nice rule of thumb is 10% to 20% of your total income.
I suggest to set aside 20% of your total income for saving, do this the first day you receive your payment, if you can do it automatically, like automated bank transfer, will be awesome, if not do it manually but don’t forget to do it.
Once you have that money on hard to reach account , you will mentally set to not overspend the remaining cash.
At the end of the month you will have your 20% of your income untouchable, or if you end with short of cash you can use 5%-10% of your savings and still have 10%-15%, but just do it if you really really I mean really need to, if you end with the 20% or more of your income one savings CONGRATULATIONS!! You are on your way of financial health.
