You're an IT teacher like you said. I'm pretty sure that you know a skill that you can offer online right? I mean you know how to use computers since you're an IT graduate, and you're teaching it as well.

How to manage your time? It's only you that can answer that question. There was a time where I can't manage my time as well, and the only thing that I did is I sat alone in my bedroom, listed all the things that I'm doing on a daily basis, and putting a time on what time will I do a particular thing. Don't procrastinate as well because sometimes procrastinating is the reason why we are lacking time to do other things. List the things that you're doing daily, and from that put a specific time where you will do that thing if it's time.

Now how to earn money from trading. If you're a newbie, forget about earning because most of the newbies in trading don't earn profit in the mid to long run. I'm not saying all, but when I was a newbie, I lost half or more than half of my capital in trading. Fortunately that isn't the case now since I know what I'm doing already, but in your case if you're a newbie then forget earning. Experience will teach you along the away, so just spend a few bucks on your first try in trading. I don't usually recommend watching on Youtube, but TBH that's where I learned trading, so I guess I'll say to watch some Youtube videos that will give you information that will help you in your trading journey.

I think in your case, it would be better if you will focus on teaching students while being a freelancer first, and then be a full-time freelancer.
