I agree with that automating your savings will help you save more. There are banks who offers auto debit arrangement on a weekly or monthly basis or whichever is comfortable to you, they will automate and put your funds in a certain services they offer like mutual funds, investment funds even in stock market. But sometimes it is hard to save specially when your budget is just enough to cover up your daily needs, and if that is the case you need to find other source of income to be able to save money for the future.
If you can process that thru banks it will give you good way to save and have some passive income, letting your money to be invested to grow even in a little amount is better than nothing, though just like you said it's tough to save when you only earning enough or if your are earning less, then you needed to look for additional sources of income if you are really aiming to save money.
It's more about how you balance your finances and how you will focus your determination to achieve what you are aiming to have a better
financial capabilities in the near future.
