There are only three things we 'have to' do in this world we have to be born, we have to die, and we have to live until we die. Everything else is a choice!
There are two ways to look at most problems... 'Oh Crap!' or, 'Good Information!,' and our choice will give us good information on how to deal with problems in the future.
There are two ways to respond to the trials and tribulations of our present and past . . . 'Ain't it awful?' . . . or . . . 'Good information!' Our choice of responses will determine our experience of life.
Meaning isn't something we discover, it is what we bring to life, either by choice or by chance.
Everything that happens in our lives is "good information" about the degree to which our choices are working for us. We can, however, choose to believe that we are a victim of the world we see, and have no choices. And, of course, we will receive "good information" about this belief as well.
As we interact with others, we can either be a person who is bringing out their best or pointing out their worst. Regardless, however, our choice is always more information about us than them.
