Crush those AAMC practice tests every other day with full time constraints. On off days, review every question you got wrong. Understand why you got them wrong. Write out a complete sentence what the correct answer is.
Keep up your motivation by understanding that if you study like I've described, you'll do well on the MCAT!
If you do well on the MCAT, you may have the opportunity to spend 4 years (1,460 days!) studying harder and longer than you ever have in your life. If you do that, you get to spend another 3-7 years in residency working longer and harder than you ever have in your life.
Then if you do THAT, you'll be a licensed physician. Your value to society will be beyond question, though your patients will probably forget that. You probably will too, if we're being honest. You'll have a comfortable, secure upper-middle-class job. People will want to date you. People you meet will be impressed with you even before they know you. You'll exude an air of authority. You'll get to do cooler things at your job than 99% of people, and if you have the right attitude, you can go to bed at night feeling like you've made a difference. You can drive a car with an MD license plate (even if you're a DO!). If you get into a high-paying specialty, that car might even be a modestly fancy one. You'll probably be able to put your kids through college. You can help society, and make a difference, in ways that very few people in the world can do. You have a not-insignificant chance of truly being the best in the world at what you do, or a foremost expert. You'll have a socially important role - one that will enable to contribute to your community, both locally and beyond. To countless people, your skills will be the difference between life and death, pain and comfort, misery and happiness. Your last name will have "doctor" before it.
But every journey has a first step, and this particular journey requires you to crush the MCAT.
