This is an observation.
When we're children we don't even seem to look for notions like motivation because we're bustling with energy. Everything can become a toy and any environment can become a playground. But it's almost the opposite after we grow up. We find reasons to get up and do something. Since the reasoning must be good enough, we don't do it if we're not convinced. There are usually no alternatives either so we just slack. Why can't we make any place a playground like we were able to do as children?
Maybe, I could argue, that playing is easier than working because it requires equipment. In that case, the need for a reason to do something goes out of the window if we have the equipment we need. But I digress. Why then do we look for motivation when all that's required is there? Is motivation just a made-up phenomenon and the need for it is only in the mind? Such that, it's a way of thinking that always requires it but never satisfies it?
What about people who are motivated? According to what I wrote in the paragraph above, they must be using the wrong word to describe their emotional state. Maybe they mean they have an adequate amount of incentive to do what they're doing. That's just motivation isn't it? Doesn't this mean that adults require incentives rather than the idea of a good enough emotional state a.k.a. motivation?
But, there's another aspect that complicates this situation even more. Even with all the incentives, humans still choose not to do that which is good for them. That which would make their lives better in the near or far future. They just find reasons like "I don't feel like it". Why? What does it matter? Don't you entertain a lot of your feelings anyways? Can't you ignore this one and do what's good for you? I think we all can and I also think that we all just don't. I guess yeah. I guess that's one of the most adult human being traits I've ever seen.
