I will take the liberty of expressing my opinion after reading your post.
I feel like I'm entering the rat race described in Rich Dad Poor Dad.
I can assume that, given your young age, you don't yet understand exactly what this means (the rat race). And I am absolutely certain that your situation is far from falling into that category. You just need to study more to understand (and I'm not talking about studying at a public university). Universities no longer teach as they did in the past; today, they only seek to train good employees who follow orders. So, drop out and focus all your attention on your English studies and on the project of teaching other people. I would say that this is the best thing that is happening to you right now.
I don't want 5 or 10 years to pass and for me to still be in the same place
To prevent this from happening, you only need to do one thing: study money, and that will lead you to Bitcoin. If you don't have an efficient way to store the energy you obtain through your work, then you will fall into the rat race category, which means you run and run but don't get anywhere. It's a stationary race, a race after paper money that erodes and degrades as you run after it.
I want to write and publish more often, because it's something I enjoy when I'm motivated
Don't rely on motivation, rely on discipline. If you rely on motivation, you will only write or work when you feel like it, and in the long run, that is neither productive nor efficient. On the contrary, if you rely on discipline, you will write and work toward your goals regardless of whether you feel like it or not, and that is what really brings you closer to your goals and makes you improve every day. (Learn about the philosophy of 1% every day).
Btw, I wrote like a 70% of this by myself (the other 30% was with google translator), English is not my first language and I think if I start writing more often I'm gonna improve my writing skills
This shows that you are on the right track. The fact that you are able to produce 70% of that text on your own is clear proof that you are on the right path by leaving public education (public university) and focusing solely on your English studies. You mention that you are already teaching, even though you don't earn much. That is also a great sign that you are on the right track. Now you need to learn more and improve your skills so that you can earn more (a higher salary) and, most importantly, be independent in your work and not fall into dependence on an employer.
First I got to experience grief for such a young age, losing a family member which was so important for me, then I stop receiving economical help from my mother
I sincerely regret your loss, but that's life. We must learn to overcome the blows it deals us, and I'll tell you something: life will continue to deal more and more blows. But if you are astute and learn enough, you will be able to weather any storm and move forward.
I'm sure that many people's mothers stopped helping them a long time ago, or maybe they never did. Feel lucky that your mother helped you until you were 18, and I'm sure that if she's not doing it now, it's because she's drowning in the decay of the fiduciary system that makes you poorer every day. And if she has more children today, it's normal that she doesn't have enough money to support them all. In this case, as an 18-year-old, you are quite capable of getting involved and paying for your own needs. (If you don't have any disabilities or special conditions.) You are fully capable and have enough to move forward.
My dad was coming back after almost 10 years out of the country.
Here too, I think you're lucky, and I'll add an example.
My father disappeared when I was born, or I think even before that, and he never reappeared to help with anything. And today, at almost 40 years old, I can say with certainty that he taught me absolutely nothing, much less gave me or contributed anything.
I don't deny that you have your reasons for being upset with him for his absence. But if he has returned and also wants to help you, I can only think once again that you are a lucky person. And especially if he has come back to show you Bitcoin (you mentioned that he introduced you to SN, so I guess he is also introducing you to Bitcoin).
but I want to learn enough to make useful contributions to this community
Your story and your words are already a contribution. Here there are people who contribute about bitcoin, economics, privacy, and life. We all contribute by being here. Don't feel small, keep writing and keep visiting SN. And you'll see that step by step you'll find your rhythm, and above all you'll learn a lot. SN is an inexhaustible source of knowledge and experiences.
Without further ado, I bid you farewell.
I hope my comments don't sound bad and that they help you in some way.
Keep studying and keep stacking SATS ⚡ 🟠
