Still in search: what completes me?

Today was long. Today was tiring. Today was almost debilitating. I almost fell apart, and shattered into pieces. But no, I was wrong. Things turned out pretty well and I had the best time of all at school today. The best part was having enthusiastic lecturers who takes the trouble to teach. Right from 1.30pm after lunch up till 5pm. All my life even during my primary school days I've never had a chance to meet people who are so dedicated and committed in teaching. I certainly enjoy Orthopaedics, putting aside the terribly-arranged schedules for classes, but having superbly convincing lecturers who inspire has definitely brought things to a higher level. I have never imagined myself sitting in the seminar room, even after 4 hours of continuous class, and keeping myself awake since 7 in the morning, still listening so attentively and involving myself in all discussions brought up by the lecturer. I can't feel more grateful to have great souls around me, inspiring me from time to time. They remind me of more important things to do in life, which of course, includes learning. 

One of the most inspiring classes that I had was rehabilitative medicine. I have a whole new spectrum of issues to ponder on after attending the class. It allows me to get exposed to another side of medicine, which is rehabilitation, in fact, a very significant part of medicine, which I have neglected so much in the past. I used to think that people who end up paraplegic are useless and they are just but a burden in the society. They never produce but they consume. However, I think I've changed my mind so much now. This morning a colleague of mine said something similar, he said that a poor soul who falls from height and ends up paralyzed, later on in the hospital he'd be contracting all sorts of nosocomial infections, and most probably bedsores as well and etc, also bear in mind that the government, or in other words, the tax payers, are paying for all charges during the hospital stay. All these sufferings do not carry any meaning so why death is worse? I was totally against this idea now because I think each life must be respected because we aren't God and we can't decide for other's lives. We have no authority to do so of course. And here comes the importance of rehab medicine. I feel that there is a reason and probably many different reasons for each and everyone of us to become a doctor, and most probably, for me, well though I still can't be sure yet but perhaps, I feel that helping a paralyzed and a many-ways-challenged person to get up and walk his own life again is somewhat meaningful. 

In ten years time, will I be part of the inspiring people who commits my life to meaningful things?
