Too much self-centered attitude, you see, brings, you see, isolation. Result: loneliness, fear, anger. The extreme self-centered attitude is the source of suffering.

Or have you once experienced a tremendous moment when you would have answered him: 'You are a god and never have I heard anything more divine.
Maybe a first love exists to reaffirm the best parts of yourself, the choices you made when you didn't worry about the consequences. Maybe a first love exists to remind you to be brave in the moment, to stand up for your feelings, instead of shrinking back in the face of potential loneliness.
Once we have a firm practice of compassion our state of mind becomes stronger which leads to inner peace, giving rise to self-confidence, which reduces fear. This makes for constructive members of the community. Self-centredness on the other hand leads to distance, suspicion, mistrust and loneliness, with unhappiness as the result.
People often expect the other person to respond first in a positive way, instead of taking the initiative to create that possibility. I feel that's wrong; it can act as a barrier that just promotes a feeling of isolation from others. To overcome feelings of isolation and loneliness, your underlying attitude makes a tremendous difference - approaching others with the thought of compassion in your mind is the best way.
