You want to wake up just when you feel so? Stay in bed till noon or start your day even at 5 a.m. Nobody is going to judge your choice. Organize your day as you wish. No traffic-jams or overcrowded tube. Isn’t it already a dream-job?
Be flexible. Be independent. We still don’t have a time-machine but you may be in control of your own time. Set priorities and follow your daily plan: combine with your full-time work or hobbies. You even might have it as your main job eventually.
