First, read the book :)
Second forget about the business aspect that might come later.
Third start to ask yourself some hard questions about your current life and its trajectory...

Like the answers?

Great don't change a thing...

Don't like the answers?
Start looking for ways to improve them and take action...

This is a mere toolbox, might not be the best for you but it helps to create a different world view

Scott Adams' book is great too
Or in the words of the great Jocko;
"Don't like it?
Make exit plan.
Execute."
