The fact is that the concept of laziness can hide a huge number of different phenomena: fatigue, depression, apathy, physical health problems, lack of motivation, lack of understanding of oneself and one’s desires, fear, slowness and thoughtfulness, immaturity and inability to cope with life.
The brain doesn't see the connection between what it's doing now and long-term results, and it starts to get lazy.
Therefore, one of the factors in the emergence of laziness is the lack of true motivation.
The brain directs its forces to preserve the body.
To do this, he minimizes unnecessary actions that he does not see as necessary.
When you are lazy, there is usually no motivation to act, although there are plenty of opportunities.
Simply put, if you constantly reschedule and postpone plans, you lack the motivation to complete them, then this is fatigue, but if you have the resources to implement them, but you just don’t feel like it, then this is laziness.
The difference between laziness and chronic fatigue lies in the energy component.
If you don't want to do anything (even chew your favorite donut) due to lack of energy, this is chronic fatigue.
If you are ready to chew your donut at any time, just not to work mentally or physically - alas, this is laziness.
