"Something" which is desired by many, yet granted to none.
That "something" varies to all people; it's beyond each other's imagination.
It can be physical, wealth, relationship, education, social status, career, recognition, and the list goes on. I lived a life whereby I put perfection as my goal in everything I do; sounds so enthusiastic right? In reality, it's just like trying to sleep on the sun. No matter how much effort you put to make yourself cooled, some heat will get through. Yes! You cannot satisfy everyone and escape from the scope of critics. I am not here to drag you down, but it's the fact you simply can't deny.
That life of mine was a stressful mess, taking all people's inputs into deep considerations till' my mind blew up. Not that I do not need them, I am truly grateful; but I just want to stand at the edge of a cliff, so I do not need people to push me down the stream.
Ask yourself; "What's your goal?"
The sky? The universe? The world?
Great answers!
Now, what's your limit?
Don't think too much because the answer is "your best" :)
So,
Just throw out your best.
Don't be drown in regret because you couldn't have done better than your best.
