The Job’s Worth Doing Well

There will always be the knockers
When its your turn to sing.
There will always be those who say
You should be doing some other thing.
Remember this is your life, mate.
Do your best right from the bell
Always remembering that if the job’s worth doing,
The job’s worth doing well.
Do not knock the knockers
They are a type of judge.
They test your courage and resolve
To stand tall and never budge.
They spur you to remember
As you hear that final bell
That if the jobs worth doing,
The job’s worth doing well.
You’ve made it to the finals
All is quiet on the wings.
Not a word is heard from those who said
You should be doing other things.
Be glad about the knockers
For giving you so much hell.
They helped you to remember
The job’s worth doing well.
(Wong, 2010)
