You're welcome. It's your lucky day
This is your limiting belief. And What I mean with that is don't get used to say you hate a subject.
I like Tony Robbins and he came up with sth that shows the relationship between beliefs and getting results you want.
It's made up of 4 things:
1) Potential
2) Action
3) Result
4) Belief
You mentioned you hate maths so we can assume your potential in a maths subject to be low. (hey i'm sorry, but there's big hope for you. I'm just explaining why you should not say you hate subject XYZ). Knowing that, you would take only a little action (doing as much as necessary, little homework, etc).
What kind of results will you expect if you don't take much action? Of course, modest results
And because you get modest results you tell yourself, your friends and relatives (also in this forum) you hate maths.
It's the same with sports, attending a job interview or anything else in life.
"Your thoughts create your future".
If you tell yourself "well, I'll give maths a chance because I'm able to learn." then automatically you have more potential, take more action and because practice makes perfect you get better maths results. With that you tell yourself "that's funny. I already knew I was good at maths".
It's like a self-fulfilling prophecy. I have many more examples but keep myself short. Hope that helped
