Yep, some new skills may seem unimportant at the time, but a person (especially a younger person) just never knows when the day may come, when a certain skill set may mean to be the difference between having a job or not.

I remember an older gentleman telling me once his father insisted on teaching him how to shoe horses. He said his father told him if he could shoe a horse, he might not get rich, but he would always be able to make a few dollars to eat at least.
