A (good) attitude training program

I happen to believe that we have the keys to controlling our attitudes and thus being able to bring more positive than negative situations into our lives. If attitudes were a white (positive) or a black (negative) t-shirt, the principle would be like putting on the right color garment when we dress, in the morning. That part is relatively easy; it's just an initial choice at the dawn of the day. The difficulty and the stark reality are that during the rest of our daily existence, we are faced with endless bifurcations and choices. Just visualize an endless succession of “fork in the roads...”

The hurdle for us is being able to make the right attitudinal choice each time one of these options rear its head and pick the one that always keeps us on the positive side. It becomes then a question of building a strong habit in taking these positive turns all day long. Every time I'll sense a shift toward the worst in my attitude, I'll try to keep that “fork in the road” in my mind's eye. Eventually, the response will become stronger and hopefully a life-lasting habit. Any better idea? Please, share it!
