I have never been a perfectionist - I have never been one to strive to do my very best. I am a kind of "middle of the road " kind of man - never at the top but also never at the bottom. But I realise now that most people are not even on the road that I am on - so while I may be a middle of the road kind of man, there aren't many of us on the road. Most are sitting on the couch!
So - for those who are "motivationally challenged" - you don't have to do your very best - just do whatever you feel like you want to do - you will be way ahead of all those who are not even on the road!
For slow runners like me - always walk for 5 minutes before you even think about running - then run till you don't feel like running anymore, walk till you feel like running again, repeat till you feel like stopping. Then find your way home!!
