If you are new in this world of programming, I have some secrets to share as per my personal experience.
If you are really good in math, that means you are interested to solve problems. This will look like a joke, but the problem solving skills in math is really important if you want to be a pro coding guy.
Start learning, start practicing and do not stop until you are not finishing your expected output.
Make small target programs daily and finish them.
Explore new concepts, framework and ideas of programming.
Work on real programming paradigms.
You need confidence to build Computer Programs. You need to practice building algorithms and converting them into programming language.
Cheers!
