Yeah, true. But come to think of it, loneliness does more good than harm. On your road to success, you've got to be alone; no friends or family.
Most great ideas come to us while meditating, and we don't meditate in a social state, it all goes down in a state of loneliness.
We set goals, plan and strategize when we are alone. Those who are in constant need of companionship are... well, I don't know what to say, but you must be truly lonely to make relevant contributions or add value to the lot.
Loneliness is the pain of being alone, and is damaging. Solitude is the joy of being alone, and is empowering.
