Is it too late to achieve my dream now or not?

I have 2 dreams actually and I’m willing to achieve at least 1 of them if not both of them.

Dream 1) is to become a red belt sensei (professor in taekwondo with 67 years of continuous experience but I’m already 28.

Dream 2) To become a scientist who’s even better and smarter than Mendeleev of the periodic table because Stephen Hawkins is smarter than Albert Einstein and I’m handicapped as well.

I just want to know if it’s too late so I don’t chase after my dreams anymore, but this time I’m really serious and not trolling around, I’m already working full time job in a bank, and don’t have time for college and also working as a commission only real estate broker
