Recharged for Work

I guess I must be idiotic to say that, to ask for more trouble... To request for more things to do was a suicidal move.... 2nd day to the start of a new work week, went into a new environment today, picked up ppl who were so weak in their academics... Sometimes, I feel that I'm not suitable for this job but at other times, I feel the passion in me burning like wild fire.... How to sustain the passion and keep on working????
