That’s what you MUST do when you’re trying to get a gigantic organization shifted to Agile because there’s nothing about it that’s easy.  Not.One.Thing.  If you’re involved you need to be upbeat, positive, encouraging and CONFIDENT.  You need to be able to recognize the small successes and understand how it fits into the larger plan.  You need to stay in the present and look back to see how far you have come and not get bogged down in how far you have left to go.  And, in those moments of doubt you will surely have, you need to be able to hide it and hide it well.  You have to be the person who energizes people.  When others are feeling discouraged and spent you have to find a way to re-energize them.  You have to find a way to create viruses like you.  It’s exhausting and challenging but, you must continue to believe.  For those moments of doubt you can’t shake off yourself or those times where something just shocks you, you need someone else who gets it too.  Someone to commiserate with but, feed you energy and remind you to be confident and carry on.  If you don’t have one of those people, find him or her now and let the person know that’s what you need.  Otherwise you will bring her down too making the journey that much harder.  Just don’t forget to believe.
