How did I end up choosing engineering? When I was 13 years old I liked to watch medical emergency programs, so I decided that I wanted to be a doctor in reconstructive surgery. When I started high school I chose the clinical laboratory specialty to get involved with a health area. For three years I studied about bacteria, viruses, clinical analysis, so I discovered that it was not good at these issues, I could not memorize so many things or remember everything, I had the worst grades. In my last year of high school I took math subjects and I discovered that I was very good with numbers, following procedures I also wanted to learn about the use of tools and similar things, so I decided to study engineering and put aside my desire to study medicine by I felt that I wasn't good enough and I was afraid of hurting someone so I chose to study petroleum engineering, I was there almost two years but I didn't like it, so I decided to change the career to mechatronic engineering because I wanted to learn about electronics and mechanics and because my desire to do something focused on the health area still existed, I wanted to acquire the knowledge to be able to perform prostheses. On my way through mechatronic engineering I had the opportunity to build small robots but that was not the approach of mechatronics at the university where I studied, I never really discovered where it was oriented, it was to learn a bit of everything and discover that I did not like mechanics so much but on the contrary I was good in electronics, in control system, in other words, in devices in charge of administering, ordering, directing or regulating the behavior of another system, in order to reduce the probability of failure and obtain the desired results , I also removed the idea of ​​focusing on the medical area, why? I do not know. When I graduated I felt that I had not learned enough, so I decided to study the master's degree in mechatronic engineering, I learned a little more about control systems, I also learned about hydrogen fuel cells a good solution to replace batteries in cars, among other things. Currently I do not plan to continue studying anymore.
