If you feel happy then also you will have to keep doing the same thing.

If you feel sad then also you will have to keep doing the same thing.

So why it is important to feel something?

I think if we don't keep any concept about happiness or sadness, then life will be much better.

Why we are running so much to feel something?

Asking my own brain and it is very important to talk with your own brain and ask it "what the fuck is your problem, why you think too much?"
