Is it better to save money in bank or invest it online, in real estate or maybe gold?
Matter of opinion how much to do. I would try to save at least some of it, so you'll always have that to fall back on.
If you have the opportunity to do both the better, your savings will take care of your future needs while your investment will give your a comfortable life. Think of that possible good outcome so you will be inspired to do what is important.
