I have my first card. How should I use it?

6 months into my first card (Capitol One Savor, $1000 limit.) I use this for every single purchase and never use my debit card anymore (except rent)

I always pay the balance as soon as it comes in. The balance at any given point is never above $200 or even $100 most of the time. Daily use for groceries, clothes, restaurants, Amazon.

Am I doing this right? Should I only charge certain amounts? Certain times a month? How can I improve my credit with my card?
