Praise or be praised?

Had my end of the year appraisal yesterday. The same old story again, I have to overcame myself before I'm able to move a step further in the company. Not just about the my position in the company now, is about the faith that certain people have in me at the company.

Should I disappoint them further? Or should I strive/soldier on and hope for the best? Or take up the challenges ahead just like every single breath you take is a fresh air for your lung just like when you're 1st come out of your mother's womb...?
