"Relationships and friends are like kites, you start out only flying your own kite. But eventually you gather more along the path of life, trying to keep them flying high together with each other. But in time the strings will begin to tangle causing the kites to drag each other down, and in some cases they fall to the ground completely. Although you try your hardest to cast them back into the sky, the decision is not yours to make but rather that of the kite and the wind that carries it."

Basically I used that analogy because I can't put the answer your seeking into actual words. Every person has the potential to achieve great things, but only a dedicated few commit themselves enough to reach that goal. And by no means should one blame themselves for another person's lack of commitment or motivation. You truly seem to possess an incredible amount of encouragement and compassion Kashima, but even with those great qualities you're only able to do so much for someone. Only the individual is to blame for their own successes and failures.
