I was reading a Design Patterns in Java programming book and came across a new phrase. I'm wondering what does off the top mean in this particular context.

Excerpt from the book:

Keep Learning

Somehow, you had the opportunity, drive, and ambition to acquire and
read this book. All we can say is, "Keep it up!" Decide how many hours
a week you want to spend on your career. Take 5 hours off the top and
pay yourself first
. Spend that time away from the office, reading
books and magazines or writing software related to any topic that
interests you. Make this practice as regular as your office hours.
