I like what you say here and especially:
"...should try our best to improve the quality of our life.
Like when additional oxygen is added to the engine of a racing car, to obtain greater acceleration, in some period of life, we need to run a sprint, we need to acquire new knowledge, which will ensure progress on the professional level, and therefore progress and improvement in life."
I agree but, of course, so many people prefer laziness and seem happy with mediocrity in their life.
I'm also lazy sometimes, but I don't consider it a flaw, but a reward for some effort and success I've made 🙂
