One of the biggest problems facing today's generation of students is the misunderstanding that intelligence is a genetic predisposition, something that's set, and something that you can never change.
That's not true.
Intelligence is a malleable thing that can be improved over time. If you believe in yourself and just do the best you can, over time your intelligence will rise and you'll start to understand things you thought you never could.
As cheesy as this may sound, your determination and spirit will make a huge difference while you're studying and going through school. The reason I did better than most students my age, who have the same intelligence or maybe are even smarter than me, is because I believed in myself. Don't tell yourself "I'm not a math person," even if you don't like math, saying or thinking something like that is extremely detrimental to you. Keep your mind open, keep studying, if you need help seek it out. If you don't ask that question when it first appears, you will appear stupid later on for not asking it. Don't fear being "stupid" by asking that question now! Make mistakes! That's how you learn!
I guarantee you every smart person out there has made mistakes, and are still making mistakes! It's human nature, what's important is to recognize and accept these mistakes, then move on. Don't let them bog you down. Just remember, it's not about some genetic predisposition or something that someone else got at birth and you didn't. It's about your determination, your spirit, and how hard you want to work for it.
Here's a really cool video that may help you later on down the road and right now-
"If you want it badly enough, you can have it, provided you work hard for it."
