If you've been lucky enough to see the new book by Paul McGee, you will know that he has something great to offer in the field of self-improvement. SUMO stands for 'Shut Up, Move On' and there's a real truth there. That most people spend time and energy living in the past, regretting something they did or didn't do, or some slight or hurt they suffered years before. If you expend energy there, then you don't have enough to live in the present or plan for the future. 'Move On' is the cry. Get going. Look forward and head in that direction. Sounds good to me.
