1. Don't speak badly of any professors-not even to your best friend. Share it with your mom.
2. Be selfish! Do what is possible to make yourself happy because even if you can't support your parents while being in med school and residency, your love for doing something you are truly fond of will put a smile on everyone's faces and give them the inspiration that they have imagined having.
3. Care about your grades based on the subject that challenges you in a healthy way. It's naive to think you shouldn't. Focus on enjoying what you learn. DON'T PURSUE a major that seems to get you simply a job because chances are: if you set up planning early, you will have a job.
4. Have ONE best friend atleast that can listen to you quarrel about life and prospects. It doesn't matter if you find this person your senior year.
5. Don't be the class clown. It can be fun at the beginning when people laugh but soon enough, you might be judged as immature and can lose favor in your department and not achieve recognition when due. Be mature, not too serious, have a good humor.
6. Go to the college that gives you a fun experience (I don't mean party but gives you accessibility to every resource you can imagine). Don't be foolish to go to the top university when you have to go through the rut of all troubles to get the education. Get your undergrad, and whiz through to med school is much more desirable than aimlessly taking gap years when you know you want to be a doctor from the start.
7. Don't let family troubles get you down. Again Be Selfish. Sometimes, parents can really over-exaggerate situations and you are stuck constantly worrying about them when really they never share the whole story with you properly.
8. Don't delude yourself that the harder route will get you the best results. You will get singed, and a lot of times looking back the lessons you learned from that are obsolete. It's better to go the straight route and not meet these problems if you know you are down to earth.
