"Work hard and you'll be rewarded as you should be". That's all I've heard since I was born.
However, there are times when I think all this life is just shit.

I see guys who worked like hell all of their lives in researching a cure to save thousands of lives, in creating devices that improve everyone's life. They own a small house, a cheap car and in case they get some heavy illness, a fundraiser is created to help them get some surgery or whatever's needed.

Then I go to the cinema and see some pretty guy reciting some lines. I'm googling his net worth, 50 million dollars. Should I even talk about how easy it is for him to get girls, how easy it's for everyone to forget about his wrongdoings because he's a star?
Just a reminder of that and I'm already losing my will to do anything for a couple days.
I envy them because they've chosen such an easy way, barely contributing to society but they are treated like kings.

How can I or maybe why should I even bother with working hard when I see such unrighteousness?
