I'm wondering...where is the limit between stepping out of our comfort zones and pushing too much to make our cfs worse or even getting into vicious circle of pushing-crashing and resting-feeling better-pushing again and never really getting better? Seems like I've done the first and I always did the second one, but I know the flaws of staying in the comfort zone and I feel very dissatisfied in it, and still I want to be disciplined and work on getting better so I'm really confused...Or should I be satisfied that I'm mentally better and be at peace that I physically won't be better than the moderate case, if I get to that point again at all with my tendency to screw the recovery up?
