As a computer scientist, electronics engineer and mechanic... in short Technician, I am often confronted with the problem related to technology, it is not always easy to solve this kind of problem, but by force, we become more seasoned and more experienced in the latter, and so for me I find that the only way to progress and be good at it... is to always upgrade to learn new things and not just limit yourself what we already understand, because the technological progress is dazzling.
