Make yourself as your rival

I love cycling. Cycling was my commuting method to go back and forth between company and home while I was staying in the USA. Even on rainy days or snowy weather even in the winter, I used cycling to move A to B. While you are cycling long distances, sometimes it is extremely exhausting and fatigues my thigh. It feels me to stop cycling in the middle of the road. But I didn't. I kept paddling on the cycle to move forward. Once you push yourself from pain, you will feel high from your cycling. At that moment, I made myself as my rival on the side of me. Your rival to make you grow is not opponents but yourself. The strongest rival in the life game is yourself. The only growth formula to make you grow exponentially is to make yourself as your rival
