You can certainly spend a little time upset about making a mistake–get angry, cry, hit a pillow, whatever you need–but it is your choice how long you stay there before you return to creating the results you want in your life.
You’re willing to put in the time and the energy to get the job done right. You’re first one in, last one out. You eat lunch at your desk, even when your coworkers ask you to go out to lunch with them. You just have a mountain of work because people see you as a workhorse so they keep adding to your plate. You start recognizing the tell-tale sign that you are not happy in your job, but you’re not really sure what to do about it.
There’s a distinction between what you wish for/desire and what you believe is possible for you in your career. You may believe that you can get A job, but you may not believe you can get THE job.
If you’re not willing to be late for an interview, you should not be willing to be late anywhere else in your life either.
Perfectionism is a special kind of tunnel vision. It’s a strong focus on something happening in just ONE way that you cannot possibly see what other opportunities exist, kind of like looking at one of those radar screens of a 30 mile radius. You think that the only options are within those 30 miles without considering that there are things happening in a 100 mile radius, most of which you cannot see just yet.
