Good Character Training

Someone once told me that waking up early and having cold showers are forms of good character training.... I'm doing both of them now.... And I think I'm doing them very well..... I no longer wake up at 6 am, but instead at 5.30 am..... I'm having cold showers every night despite the presence of a Ariston heater in the toilet. Not by choice of course! The @#$% thing does not work! To add to these two forms of training, I'm also sleeping late.... May I ask if that constitutes part of the good character training programme?
