My key takeaway from this book is that you can do anything if you are determined enough. There is no room for complaining and passivity if you wish to live up to your true potential and enjoy the #goodlife without regrets. And ultimately:

"The measure of our lives is not determined by what we achieve for ourselves; it's determined by what we share, give and contribute to others. Do whatever you can to put yourself in an environment that focuses on contribution, not complaint. Giving, not getting. Service, not self-importance." - Marie Forleo
