Where to start?

So I've followed crypto for a while. I mainly listened to my friends about it. They got me to buy some NEO and that's about it. Now that I've been researching blockchain technology it's changed my life I swear. I'm a young guy I'm only 18. I currently hold 10 NEO and a Litecoin. I have run into some personal finance issues and for a few months won't have any spending money. Can anyone give me any tips on trading/mining for Ethereum? This is the coin for me and I don't want to miss out on the future.
