Is there a value for a single moment of mindfulness (without others) ? what is the value of a single moment of mindfulness- and is it worth anything if not combined with other moments 

when i do a good action to help others even a small one it has its benefit to the other without even looking at its affect on the practice even 

even if i do one deed like washing the dishes of the family than i dont do nothing for 4 months its worth something  

if i meditate for 30 minutes or  be mindful while doing some action for 30 minutes   and than i dont do meditation or even be mindful  for 4 months   -  is it worth something ?  why you say so ? 

(there are so many teachers talking about the importance of consistent practice which makes me think that its not worth anything) 

This is a continuation of a precius question i ask which is very similar but not exactly the same : 

Is there a point for a not continues practice?
Value, let's face it, is an idea - not to diminish the question. Value can be attributable to all and everything that occurs, whether once and forgotten, or consistently applied. 

All that can be found is mindfulness, whether realized or ignored. No moment, or what appears in it, can possibly have a beneficial or detrimental effect on some other moment, though a clean sink is bliss itself.

If one's present course of practice is intermittent, it is beautiful. If one's present course of practice is consistent, it is beautiful. If we tie our quality of practice to some preferential outcome, there is binding.

If we fail to see or appreciate the fulfillment of things as they are, our very commitment to practice can reinforce the myth that we are somehow less than enlightenment. Presence is awake, this is irrefutable.
