Happiness cannot be attained by wanting to be happy - it must come as the unintended consequence of working for a goal greater than oneself.

As for the concept of collective guilt, I personally think that it is totally unjustified to hold one person responsible for the behavior of another person or a collective of persons.

It is always important to have something yet to do in life.

What you have experienced, no power on earth can take from you.

If there is meaning in life at all, then there must be a meaning in suffering. Suffering is an ineradicable part of life, even as fate and death. Without suffering and death human life cannot be complete.

Suffering presents us with a challenge: to find our goals and purpose in our lives that make even the worst situation worth living through.

Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom.
