My Dream...My Future

Since I was a kid I dreamed that I will become a doctor. When I was in preschool I also play as a doctor with my neighbors.

There was also a time that I asked my self that why I'd like to become a physician in the future. I don't why? But like being a doctor and serving people is in my veins.
Now that I'm a senior-high and picking my course I'm determined to continue that dream. But there are some questions bothering me, like can I do this? ; can I finish this course? This are some questions that makes me worry.
To become a doctor there a some stages or levels to pass first you have to be a college graduate then pass the board exam then you have to finish medicine then again there is the exam to pass o be a licensed physician and you have to have your specialization and get a job... that is according to a friend of mine, hahaha.
However, I will continue as long that I can and there are no major financial problems.
