What pieces of information would you use as stepping stones? What do you wish you have known at age 18 that would have contributed to more success? Where would you have invested more of your time and knowledge into?
It's not what you know, it's who you know. Most of my biggest wins have come about through my network of relationships. Make time to develop relationships with people and understand what how they can help you. Often it is not you asking them for help in your career or goals, but they will help you by virtue of their knowledge and support. Creativity is more important than knowledge as Einstein said, but relationships power progress.
