Budding investor here. Would like some advice

Hello all, 18 year old budding investor here, as the title states I am interested in beginning my investing journeyand needbsome advice or general tips. A little backstory, my friends invest in multiple things from day trading to ETFs and I figured why not start too at a young age. I try to ask where they get their knowledge from and they were kind of vague saying lots of videos and websites and of course this didn't really help me. I feel like if I just start, I'll be blindly diving in headfirst. All I know is that I want to start putting in 50€ a month into ETFs but I don't know which ones and I dont know much about ETFs. So if there are any reccomendations it would be greatly appreciated. Now I realise ETFs are a long term steady return but I would also like something that I can be active at rather than putting some money not doing anything else and it's just slow and steady. I'd like something a bit faster or some more risk just so I can gain experience first hand. I am away right now volunteering and have lots of free time so something than I can just spend a couple of hours at a day would be great. I have about 300€ that is available for me to start with but I would like to know if anyone has suggestions for good places (preferably) to start my research or ways to invest I would be eternally grateful. Thank you so so much
