My best friend introducing me to RSD back in college, I've since gotten married and outgrown that whole thing but it was massively transfomative in terms of building real confidence, learning to be the best version of myself, taking risks.
Jim Rohn and his words had a lasting impact on me. These days GaryVee and Tom Bilyeu color a lot of my thinking. Tim Ferris inspired me with his experimental mindset because I'm a bit like that too. Tony Robbins too because he has such a great mastery over his emotions despite all the things he has faced in his life.
