Stress and short sightedness

I know quite a few people who are stressed all the time. One of them went to a stress management class and heard that there are three types of people when it comes to stress: the turtle, the hare, and the thoroughbred. The turtle can only do one thing at a time at his own pace. The hare jumps from task to task, completing some but distracted away from others, and so becomes stressed. The thoroughbred completes a task at a time while avoiding getting distracted by other tasks and thus doesn’t get too stressed. So the hare exemplify my friends who are stressed all the time.
I think I belong to the thoroughbred category. I can even do more than one things at a time and not get stressed. Sometimes I even enjoy the pressure of the deadline. But this isn’t because I’m some kind of a super animal like the thoroughbred. This is because I’m short sighted.
One of the stressed ones puts pressure on her self. Like the others, it is a self-imposed stress, and she does so because she wants to get to where she wants to go in life. She has a rough idea of the path she wants take and what she needs to do get there. That’s why she gets stressed. The stakes can’t be any bigger! I on the other hand spend very little time thinking about what I want to do in the future. I think a lot about how I want to feel and what kind of person I want to be, but not about a career path. When it comes to a career, I’m short sighted. I simply don’t think about it that far into the future.
This is not a virtue but a flaw. Though thoroughbred best describes how I handle stress, there should be a different category to describe someone like me: the donkey. It handles the stress just like a thoroughbred but it sure won’t get to the goal any faster. It might not even know there is a goal.
Now, can the donkey become the thoroughbred any easier than the hare? I doubt it. The later transition requires refinement only in method, whereas the former requires a change of philosophy. But then the donkey isn’t too bad of a position to be. I heard they are very dreamy and romantic animals.
