Laziness (also known as indolence ) is disinclination to activity or exertion despite having the ability to act or exert oneself.
Laziness is a habit rather than a mental health issue. It may reflect a lack of self-esteem, a lack of positive recognition by others, a lack of discipline stemming from low self-confidence, or a lack of interest in the activity or belief in its efficacy.
How Laziness Comes In:
We’re all inherently lazy, even if you think of yourself — or have been branded by others — as Type-A. You’re basically just a skin-and-bones functionality of your brain, right? (Think about the first thing that comes to mind when I say “brain dead,” and then try to determine how close to a human being that image is.) Your brain is inherently lazy. Its evolutionary function is to predict threats and remove you from those situations. That’s tough work, but on top of that, it doesn’t want to do much. That’s why real human growth (and change) is so hard, in a nutshell.
Laziness is in our nature, and it can actually prove beneficial for the body and the mind. Besides, it takes skill to be the right kind of lazy, and, according to several studies (that's right, I'm dragging science into this), some people cannot even help it.
Call it laziness, sloth, ineptitude, idleness, or whatever you like but the idea of doing nothing when things need to be done is often considered to be a sign of weakness or shirking.
