Read regularly.
Read broadly.
The Good Book is good. It is always worth reading. There are a good many other books worth reading too. Read numerous authors. Read numerous genres. Read in other languages if you can.
I try to have about four or five books going at a time. One in the Bible. One for pleasure. One for learning something new. One in Greek. One for meditations, like a Psalm or poem or lyric (which technically wouldn’t be a book, but you get the idea).
Reading is a good habit for a good life. It will expand your mind, broaden your interests, and expose you to other worlds. Reading has changed my life, and the change has certainly been for the better.
