Just be who you are not today, even for a day - another character or.., be creative, not to do with original, cultivate a new habit or style, unexpected solutions. Try something new, get out of your comfort zone, get experience, just enjoy everything as a beginner, find new ways to get things done, even run into a restaurant that you totally got not idea what you will be serve.
I always love this feeling, it makes the day more exciting, and interesting. I will just hop up the first bus, I know my route will be change, who cares, I will adapt and adjust to fit, if I am not happy about it, I will shift, usually I am satisfied with my own option, and I gain some new experiences along the way. Lower some expectation will do somehow good.
