"If you accomplish something good with hard work, the labor passes quickly but the good endures; if you do something shameful in pursuit of pleasure, the pleasure passes quickly but the shame endures." Musonius
On occasion I see you not wanting to expend only a little more energy on an endeavor, and instead choose to cut it short before it is solved or finished. Let me assure you this amount of effort will be insufficient to accomplish most things worthwhile in life. If you let your mind become lax, this has the same effect as losing it.
There might be disagreements over politics and in many other matters, but the one thing that everyone seems to understand is that working hard is a favorable trait. This favorable trait sometimes pushes aside bias and hate. Unlike talent, hard work isn't something you're born with, so it doesn't fuel envy. Being a hard worker is something you have direct control over and is a mark of an honest earner.
You need absolutely no skill to work hard -- it is a decision made mentally and then is physically executed. There are no necessary years of training, only the willingness to move forward even at a snail's pace. But a snail's pace is remarkably faster than not doing anything at all. Few things in life are that simple, powerful, and rare.
What do you gain by working hard? The same that a person gains when he has shot an arrow to the moon: a sense of accomplishment. Yet people strive to find themselves through travel and leisure. Little do they know that what they are seeking can be found through work, even, or should I rather say, especially, mundane work.
Whenever you see people running away from what is difficult, you must resist that reflex and instead run towards it. Your conscious act of wisdom and bravery will pay off multi-fold. You might go slower but you learn more. You might be done later but your work will be more refined. You might even be all alone but that is because you are farther ahead than anyone.
The gods create. They create for creation's sake, lest they too become mortal and vanish into oblivion. Where would Heracles be if he never went forward and struggled and triumphed, but instead decided to stay in bed or lie on a beach? What is there to talk about, what is there worth remembering?
Show, if not for the gods, for your future self, who will have long since forgotten the cost of labor, but can still see and feel the lasting achievement produced from that labor. Your future self would have great respect for himself, as you should have for yourself when you strive to do what is right and go the extra mile. The difference isn't always clear to people in the amount problems you faced and conquered. What is always clear is the end result, the obvious amount of care and attention you gave it beyond what was expected but right on the mark for what is needed.
"Do not tell people what they should do when you do what you should not." Musonius
