Grant Cardone has laid out his experience in a nutshell, and I've written out 9 key takeaways for you so you don't have to spend tons of time on the whole book and read it in 5 minutes!
1. Read a book like it's worth a million dollars
A simple but important rule. Try to apply it to any self-development book you buy or download. Make yourself believe that the cost of the book is huge, and you'll feel the urge to absorb every line of it. Give it a try!
2. Don't compare the current situation to yesterday's situation
Many people say that "things were better before" (and the trees were taller and the sky was bluer). But in reality, nothing has really changed for better or worse, it's just different. Life has changed, the market has changed, but it doesn't have to be resisted.
If you want to stay in business, adapt to the new conditions. Control your beliefs, your train of thought, and remember that everything around you changes.
