Human nature does not want to feel tired of working to earn money. Everyone wants the same thing, but many people don't want to give up and prefer to keep looking for work rather than expecting quick results without effort. They know it is impossible unless they have been rich since birth and will never feel the slightest lack.
Gambling is indeed entertainment and nothing more. People should know that so they don't rely on gambling to make money. So it is better not to think about making gambling your main source of income because it will be difficult to get it. And we have more potential to experience more losses than to win.
I think human nature does enjoy work.
When you finish something you usually feel good. Accomplished.
Whereas if you are just laying on bed you usually feel bad.
