All we really need is a few short peak experiences (within a moment Krsna conciousness can be had or not after millions of life-time) to bring around to full Krsna conciousness or we can waste a lot of time; maybe many lifetimes simply loitering in this world without full-blossoming Krsna conciousness.

Agree...but the problem is age-old and universal: "The Spirit is willing but the Flesh is weak".
