I do believe that even before you apply for the JPA scholarship, you must already have in your mind the implications of doing so. The 10 year bond. The uncertainty of the country JPA would send you to. Your real heart and motive for pursuing medicine.
What I would say is that if you want to apply for the JPA scholarship (medicine), do be prepared for difficulty, times of regret and doubt, lots of sacrifice, and a lot of moulding of your character and toughening up. It's not going to be an easy road, and you have to have a real heart for serving your fellow citizens in the government hospital. Enduring suffering, not being respected, long hours, etc. Many of us JPA scholars (me included) have times when we wonder whether we really made the right choice in applying for this scholarship, but we keep pressing on and are grateful that we (unlike many unfortunate JPA scholarship rejects) have been given the chance to serve the government and we are ready for the responsibility to serve our nation for ten years (or more).
All the best to fellow JPA scholars taking medicine! May we endure and serve the nation!
