Woopy, I took a look at some of your other posts. You're clearly having a hard time picking a major and further you state that you never really had an interest in medicine, you're bored in your math/physics classes and with the finer details of biology. You prefer the macroscopic to the microscopic, animal behavior to molecules and you're already talking about burnout.
Why, then, become a doctor? The money? I don't see any other reason. Think about this, though -- how do you intend to get through Chem II, OChem I & II and Biology with that mindset? How will you not burn out if you're taking subjects you hate... biochem, microbiology, immunology, genetics, etc? And that's just your undergrad career. You'd still need to get into medical school (good luck acing the MCAT if you've forgotten everything a week after each final) and THROUGH medical school. That means more classes about subjects you hate and can't be bothered to remember.
Even if you do make it into/through med school and into an internship and residency.. how will you hide your flagrant ignorance when they tell you to do something and you don't have a friend there to give you the answers? Like you said you've deceived your teachers into thinking you're smart, you've tricked them into thinking you know what you're talking about -- but more than that you've deceived yourself.
You've convinced yourself that you'll get some dream job where people will pay you 2-3 times as much as they pay everyone else.. for what? Think about it. What are they paying you for? They're paying you for knowledge, a skill-set, abilities that other people don't have. If being or becoming a doctor was easy, everyone would do it.. and a lot of people try. Compare the number of hopeful, save-the-world and buy-the-lexus "premeds" to the number of people entering good med schools with 4.0 science GPAs (rather than 4.0 English) to the number leaving med school with equally impressive resumes.
Most wash out. While you're at it, read up on some of the recent news stories surrounding the realities of law school.. the fact that people are entering with dreams and leaving with debt. They're being told that lawyer = money, they're NOT being told that this is only true for the best students at the best schools who know the best people. Read up on the classes required for EE and you'll see why your friend studies so hard to get those As.
Do the research, understand that things get harder and if you're not willing to put in the hours (as you've clearly stated you want to give up after 10 minutes of studying) you will not make it. Doing what you dream and making $30,000 is better than failing out of med school with a few hundred thousand in debt. Alternatively you could get your **** together, realize that money doesn't come easy and put in the time to study.
