>>1 effort. Everything takes efforts. All skills take practice, you don't have to be naturally gifted or talented to excel, all you really need to do is out in the effort. An example from my own experience would be me with math, I'm not gifted, my parents aren't either, but I put in the effort to learn as best as I can and put in the effort and asked a lot of questions, now I'm in calculus.
You can research some methods to get you motivated and find what works for you, all you really need to do is put in the effort into studying. For me, I make detailed notes, use the reward system, stuff like that, and it helps.
I hope that this helps~! Good luck!
