Suffering

Why do we choose to suffer? Anytime when we are doing something and want to do something else do we not complain, criticize and suffer? When we judge and find someone something wanting, lacking are we not choosing to suffer? When we split yourself into two, wanting to do something but forcing ourselves to do something else and not accepting the choice do we not suffer?

So then why do we choose to suffer? Do we really choose it or is it a habit, which is socially acceptable.. to complain, to criticize, to judge others instead of letting things be the way they are....
