Let’s just say it like it is, not everyone can be a pilot. It’s not easy, there are certain requirements not everyone possess. It’s nothing personal, for example, I can’t be a pharmacist or a lawyer? It makes sense, it’s too late, I’ve already made my “life” choice. Wait, why can’t I be a pharmacist? I can be a lawyer if I wanted to. It’ll take a lot of time and effort but if I’m passionate about it, I can easily do it. You know what? anyone can be a pilot. Still though, like any career choice in the world, there are a list of requirements you’d need to fill.
