I vaguely remember my high school philosophy teacher telling us that Kant had lived freely in his early years, he drank a lot, partied all the time. But after reaching a certain age, he arrived at the conclusion that he had a duty in the society, so he organized his life rigidly. He told his servant to wake him up very early every day at the same hour. He worked and ceased partying. He carefully planned all parts of his life, for example for enjoyment he invited friends to his house for dinner. I think taking Kant as an example could be flawed here. He didn't organize his life in routines to benefit himself, to make him more productive/happy etc., he organized his life to fulfill his duty and I personally don't think that he was happy in doing that.
