If only I have known

If only I have known
The gift of hardwork
And the pain of failure
If only I have known
I would have studied my best
To overcome the pain of failure

If only I have known
Your space in my heart
The pain I would suffer without you,
If only I have known
Then when we had misunderstanding
I would have compromised

If only I have known
Your place in my life,
Without you a lonely life,
If only I have known
Then I would have apologised
For all the pain you been through
