Credit Score

Hi all! Forgive me, I'm new to the sub and am unsure if questions about credit are welcome.

I have a score of 762, am 22 years old, have established credit by having utilities opened in my name, as well as by using my card and paying on time. I've never missed a payment and never been sent to collections.

I'm very ignorant to the in's and out's of credit, but obviously know that I have a decent score for someone my age.

My question is in regard to what I can do at this age to continue to raise my score into the 800's?

Any advice would be greatly appreciated!

Thank you!
