...how can you be the cause of growth?
Bad stuff happens in business all the time. You don't know it yet, but it's happening to your job right now.
You have a choice at your inner core. You can choose to be a victim with all the attendant energy-sucking gossip, complaining and recruitment of people to your worthless cause. The leader, however, is the person who recognizes this possibility and consciously rides the wave of taking responsibility.
Be clear here. You can't be a victim AND be the cause of growth in difficult circumstances.
When your integrity is tested like this, get on your surfboard above the waves, take responsibility, forgive, let go of the past and create.
And above all, show those stuck in the waves that they too can surf for the greater good. That's leadership.
