Well, let's start...this knowledge pursuits and trying to improve or increase English skills is about me. FOR REAL!
Well let´s start....(by my pursuit of knowledge etc...but I am going to stick to your original format)
This knowledge pursuit or these knowledge pursuits (perhaps you meant pursuit?)
English begins always with capital.
I leave FOR REAL as it is, for I think it´s not for academic purposes, TOEFL etc...
Many people would mistake "FOR REAL" for an equivalent to a shout or something like that.
I do remember that my first contact with English was by way of my uncle who's a teacher at Yazigi.
[if you have more than one uncle, you can also say "by way of an uncle of mine".]
We never had such good relationship but I used to read (or try to, LOL) his books when he was not at home. Later that came the real contact at high-school, to-be verbs and all those boring grammar stuff (I used to think) just came into my mind. At the same time confusing me and dropping a question, couldn I speak English someday?
I do remember, if you mean some kind of emphasis here, if not, just "I remember" would do.
LOL is normally capitalized, since it is an acronym.
I've been always surrounded by people who wanted to learn English and it really helps me a lot.
[I leave that this way, but be aware that many people would get confused. They would ask, what helps you a lot? the fact of you having been always surrounded by people... or you meant that you have always be surrounded and by people who wanted to learn English, and it (English) is what helps you a lot?
In 2005, my grandpa enrolled me in a private school (the school's name was International House then moved on to Yazigi franchise). It had awesome teachers for a beginner guy. I studied there for...I don't know for how long it was, maybe...8 or 9 months, it was then that my grandpa died. [It] was hard to pull myself together and short money were some reasons that my mom lockep up my course.
“I” is always capitalized.
Was hard to pull myself together and short money were some reasons that my mom lockep up my course.
This part was a bit confusing to me, perhaps you meant the following?
It was/became hard to make the ends meet/it was hard to support the family and the short money were, among others, reasons that led my mom to interrupt/freeze (trancar)/interrupt/stop (me tirar do curso) my course .
Anyway, you made great strides for a self-taught guy, congrats on your writing skills.
