Listen

The thing about routines is that even if what you are getting thoroughly bored with is good for you, you will get bored anyway.
And you wont rest until you change it, and you will fall ill trying it, but you will keep at it doggedly.
Maybe this trick was immensely useful thousands of years ago, but not now. Not with deadlines, appointments, weekly grocery shopping trips, visits from relatives, sudden but expected costs.
Shut up and put up with it.
Dont waste time trying to get yourself a makeover as well.
