Is that really true? I believe that. We are naturally lazy, that's the way humans are. Some stay lazy their whole life and there is nothing bad about it. It's everybody's choice what he/she wants to do.
What I discovered for myself is, that if you are first of all doing what you like is very important for your inner satisfaction. I know a guy, he works in the gym since nearly 10 years and he is the very happy with his job. Some people might say, that this is not a great job. I think differently, this guy knows what's the most important in life and he is living it: "Finding what you like, what fulfills you, what makes you happy when you stand up. That's the real magic.
I respect this guy, I sometimes talk with him when I am in the gym and I think he is a great person.
He is way ahead of many other people who are conditioned to have a great job, that's honored in the society and gives you the feeling of being more valuable. If you look at those people in more detail you sometimes discover that they are not satisfied at all (I don't say every person, but I think that much to many people are conditioned by the society, by their family or other external factors that are not good for them).
I myself was in a job for nearly three years that I did not like at all. I mean I liked learning new stuff, that's just my nature, but I actually didn't like the topic. It was boring, I could not see myself reading stuff about it in my spare time, only if my boss told me I had to read that and that, Moreover my boss was a complete asshole.
