I quit because i was not good enough to make it. I was always thinking that i´m lazy and that others work hard. But i was just learning day and night without results meanwhile my classmates were enjoying life.
Class mates told me "give it a half hour a day and you´ll make it" but they didn´t know i give it everything, sometimes i just forgot to eat, or sleep for learning so long and i just fell unconscious with papers in my hand and after waking up i continued and i barely made it, but after few months staff keep getting progressively harder, i decided not to come back again after two math class. There was an exercise and it took the profesor 90 minutes until it was finished. Profesor had lunch break and after that we came back to the class and i was hopping she will start explaining it slowly again, i was hoping that it´s simple and i just don´t understand it. There was still the same exercise all over the board that was 4x size of normal school board. After clearing the board she only left the last solved piece from exercise and she continued solving it another 90 minutes and other students were helping her. And i had not even a clue what is going on.
It was that moment when i knew it´s over.
I also fell for a trap, because i made the exams to the university and these exams were pretty easy. I was full of hope, but university just wanted to collect money from state for every accepted student.
