Post graduate

I never think about this topic before although if I finish this career I think that I will practice about a year, this year will be as a rest for the study, although I will learn a lot of about my profession and for this reason I think that I will choose a post graduate, I think do a master's degree of pharmacy that means that I will have to do a thesis, this will be a challenge for me as person and as professional , I should finish master's in two years, then I think that I will work in a laboratory, and there I will discover new chemicals (in theory) or find new drugs to help people ill or vaccine to prevent new illness, If I can do one of this, just one I will drive and accelerating the progress scientific and technological.
In many years after and if I would want continue studying I think that I would try do a doctorate of pharmaceutical sciences, In eight or ten semester I should finish the doctorate, The more big problem about choose a post graduate is that I will need a lot of money, almost four million pesos, for each one of them, for this reason I will have to work and study at the same time,although I am not very sure if I can do both, I think that stress control will crucial for me.
