My husband has an expression he calls 'duty dating.' This is when you are a bit rusty and the nice old lady sets you up with a niece with whom you will likely have nothing in common. Go on the date. Go with the best intentions. The nice old lady made an effort. You could use the practice, and perhaps something golden will come out of it. You might like the niece, she might introduce you to a new restaurant, or to your future wife. If you don't go, you will never know.
By analogy, if you could use some practice interviewing, and have the time, by all means go. It might be good to work out the kinks in how you present yourself in jobs that you don't necessarily pine to land. You might actually surprise yourself, land, and enjoy the job.
In the future though, if you aren't desparate, and don't have the support to take a job too far away, apply to those positions which are nearer to you.
Good luck to you and yours,
F. B.
