Choose a 24h period. For all of those 24h assume that whatever happens to you you can work it out, resolve it and come to a decent conclusion. Be resourceful, courageous and stoical. Be a volunteer not a victim. Seek solutions not problems. Work with people and understand them. Do not blame, complain nor even sigh heavily.
Give it a whirl.
