I’ve read this book more than once, and continue to pull it out periodically. There is no doubt that Stephen Covey changed the world of self-improvement forever in 1989 when he published The 7 Habits of Highly Effective People, and over 25 years later it remains one of the most referenced books in its genre. Covey provides amazing lessons that have withstood the test of time and remain relevant today.
Good solid principles. Not ground breaking, but it does include many good ideas for changing your life through changing habits. I enjoyed the goal setting / dream setting portions. If you do the activities in the book to describe your dreams and goals I think that's a major step toward achieving them.
Crushing It covers all the motivational bases. Gary drills into major social platforms and how to get the most out of them. I love this book and I recommend it to entrepreneurs or those who want to get there. One not so positive note however, Gary speaks about working lots of hours so balance your work with quality of life decisions.
