Regret can be a terrible addiction. Those who suffer from it so often become bitter and full of self-pity.
It is an emotion that serious entrepreneurs cannot afford: they must keep pressing onwards and should not look back with remorse, dwelling on errors of long ago.
As Alexander Graham Bell, inventor of the telephone, said: “When one door closes, another opens; but we often look so long and so regretfully upon the closed door that we do not see the one which has opened for us.” Entrepreneurs must learn to manage the conflict between constant experimentation – which means lots of painful mistakes – and a fear of failure, which can lead to paralysis.
