What do I want to achieve in life? and Introduction!

I aspire to obtain a degree (PhD) in physics, genetics, medicine (not specified, but preferably a surgeon (thoracic, general, etc.)). I would also like to advance in my piano playing. I have a passion for running, mathematics, and science (expressed by my blog's topic); therefore, I aspire to continue incorporating them into my every day life. I am currently in the 10th grade. I was running in the varsity team in Cross-Country during my early 10th grade year, but health complications complicated my running and I had to cease my activity. I run a few times a week, but I have not fully recovered. There are also an abundance of ambitions that I want to accomplish (i.e. run 40 miles, earn three PhD degrees, etc.) and I believe that if I organize my life adequately I can accomplish such. 

Running Is my Passion???

Many individuals who excel in running are pressured into joining a cross-country or a running team/group. I for one run because it is my passion not because I excel at it. If you are a decent runner, but prefer basketball then join the basketball team. Peer pressure or self induced prefer should not interrupt your decisions to pursue your passion. I enjoy running, but I do not advertise running to all of my friends (i.e "Running is AWESOME, you should join the Cross-Country team!) If you are passionate about something then you will surely enjoy doing it many days of the week, but if you do not enjoy something and only do it because you are pressured to then you will feel as if you are being tortured, that your life slips away, that you are continually falling down a bottomless pit. Overall, what I am attempting to convey is that you should only participate in an activity that you truly enjoy.
