Craving Comfort Zone

One day, happiness comes,
After sweating my blood for a long time,
As such, I felt, I believed and worked,
But that happiness came and went out,
Till then, I never knew I burnt out.

Looking at my past, 
I feel I'm wrapped up in cotton wool,
When someone flashes me about the future,
I used to think, why should I make my brain pain.
I didn't know I was in my comfort zone,
When I knew,
I strive to come out,
But I was already handcuffed with it.
