Focus on marginal change. Each day, work towards improving your health, career, spirit, and emotional state. Don’t worry about the end goal or what’s going to happen in the future. Each day has a sufficient amount of burdens to occupy you. Tomorrow will take care of itself. Martin Luther King Jr. once said, “If you can't fly then run, if you can't run then walk, if you can't walk then crawl, but whatever you do you have to keep moving forward.”
