Why you don't like exercises? Because they are exercises.. based on effort and control. You're thinking about making 13 of them or 4 series of 15.. instead of just making this one. Just making this one step. Fully, in quality.
Why you don't want to get out of bed and say you are 'depressed'? Because you're thinking about having to do this or that or not having to do that, a whole day of errands, meeting with the boss, arranging a bank loan.. while all you have to do is put ONE LEG OUT of the bed, Just this one step.
Always only this one step. And with the best quality. That is enough.
