Since primary schools, my intention was to study Systems Engineering. I entered the University with the first option in Computer Science, but my eyes were overwhelmed by the inclemency of the TCR, amber or green monitors, so I dropped out for a semester and could not return to study it. I went on to study numerical analysis. And years later, I ended up in a Classroom, and it's been wonderful everything that's happened… I'm sure it was the right thing to do.
I saw one of these recently at a factory site :D
Perhaps because it turned out okay. What if it hadn't? Or what if the other path would have been better? surety is only when we know the result already :)
