Hi, and welcome to this infinite but fascinating world!
Your background seems to me to be quite good, your way of thinking and your discipline are allies that will be very useful to you when your real salary arrives.
Perhaps one piece of advice that has helped me personally and that I wish someone had told me when I was 20: set ambitious goals and do what it takes to stick to them.
There are enough reasons to spend money, but at your age I think it’s more important to enjoy life and learn as much as possible without having to deprive yourself. I think it’s important to have a goal that makes you want to go beyond and have a reward in sight.
It could be putting aside some money to finance (in cash!) your next motorcycle or a car you like. It could be saving up to buy an apartment in Switzerland. There are as many goals as there are possibilities.
