Success is a marathon, not a sprint. The only way to truly prepare for a marathon is to train, to practice, to run. You need to get out on the road. You need to put in the miles. It takes time, it takes effort, and sometimes it hurts a lot.
As the great marathon runner Juma Ikanga said after winning the New York Marathon: “The will to win is nothing without the will to prepare.” You can want to win more than anyone else in the world, yet if you do not put in the work, it will not matter.
