As we have heard;
Nothing good comes easy
That's a sensitive saying.
What's good?
I'll define good as anything useful for a particular purpose or function.
Smart right?
Yeah, it should be good if it benefits me. What if it doesn't benefit me but others?
That would be bad on my side, right?
A good thing must not be beneficial to you, that's why they have the word Charity.
Doing a charity work is good. You may not know the reward but there's always a reward for your charity work.
Doing good today doesn't mean that you're known to be good. It only shows that you can be good to others and at the other hand, those which you've been good to see you as useful and beneficial to them.
That's another smart move. You could be a politician tomorrow. Lol.
Being good makes you fell good, feel free. That's why life is good.
