Western runners can learn a lot from the approach to training Kenyan runners adopt.
First, Americans have a mentality that you are only as good as your last race, or as good as your last workout, and carry this with us from race to race and workout to workout.
However, when you talk to Kenyan runners, their approach to their fitness is the opposite. They think you are as good as your greatest day, even if you have not had it yet.
Likewise, Kenyan runners learn how to leave their workouts at the track or on the roads. They train hard and push the limits during the workout, but as soon as it’s over, they forget about it—good or bad. This allows them to move on after a bad workout and not let it linger and bleed into their next race.
When you have a bad race, review and assess it for 20-minutes. Learn from it. Then move on and get on with life. Your life isn't all about your races.
