For me, it was seeing IM TX every year outside of my office. I would go on my normal lunch runs and see all the athletes coming to the expo or doing their practice runs/rides. I would see some of the athletes and tell myself if that person could do it, I can do it. So after years and years of telling myself this, I finally got my butt in gear and hopped in a pool and bought a bike. No other real reason except FOMO. LOL.
