<prompt> Human: Questions first: - what are stupid mistakes i should avoid, especially mistakes that come from doingchanging nothing. This is the main reason why im postingasking this.- what are important steps i should take to improve the situation further in the future? Im in the EU, but you can ignore the conversion rate i think.Im a student, and im in not one but three very lucky major situations that im very glad of: - Im in the EU, so i have very little insurance cost, studying cost, etc. university fees are 60year- I have 0 debt, because my parents help out with studyingliving-costs. 800Month - As of recently, i have 100k from my grandparents. That sum is in stocks, etfs, mostly long-term instruments, just sitting there. Im not taking any of the dividends, it just compounds. I could change the composition but so far i have not touched this at allBackgroundabout me: Fairly normal student otherwise, 21, studying, should be finished with my bachelors in 2years. Major city 4m people. Studying a STEM-field thing. Have some money in a savings account 2000. I pay 420month for a lovely shared apartment, which is very affordable in my city. While I dont have a regular job right now, i had one until recently400month and im actively looking for one tooalso 400month. I have a small thing on the side where i draw stuff for people, but that is very irregular, 0-100month.There are absolutely no major costspurchases i plan in the near or near-ishmedium-term future 5 yearsI dont know what additional information is relevant.  <response>: I know this is personal finance, but my suggestion would be to focus on what you will do after your studies and invest any extra in that direction. Whether it is an internship, foreign travel, an online course. What most people in your situation in Europe regret is not wasting the little income they had in Uni, but rather the time they wasted. The time to try things, the time to learn stuff, the time to make mistakes and recover.
