It depends.......does your daily life require you to use the skills that you are weak in?
You might not be strong in getting the most value for your money........But it is certainly a valuable skill today.
You might be weak in home repair, but it could serve you well.
Personally, I am one good cook. It would be to my benefit to become a skilled meat cutter ( butcher), a lost art. My "value" in the work place would go up!
If you are a surgical nurse, who does no cooking or meat cutting...........YES, get all the education that you can, become the BEST surgical nurse that you can. I might be the next patient, and I certainly want a highly skilled pro.
I can not imagine, that I could not benefit, from knowing a little about everything. At least, let me stay in the conversation!
