Just remember that money won't make you truly happy, OK?
It will pay the bills, and will set you with a nice retirement. Of course, there are other things that will make you very happy like helping poor people. Maybe traveling overseas to help the poor? It will be nice to help your family, parents etc...
Make sure you will love doing ortho. once you are done. There's nothing more depresing than studying this hard for yrs and then do such a long training, only to hate driving to work.
Money is nice for few days, and then what?
I totally belive that is wrong to do anything just for money. We have a hole to fill up in this universe. We have a purpose in this life. Find yours so that you are truly happy.
Good luck and be happy. Life's too short!
