[Serious] Generally speaking, is philosophy a worthwhile subject of study?

[brewer]

Yes, I think food for the mind is important, but that food is found in many ways that do not need to be based in philosophy. Can a mechanic improve his skills with learning more and better techniques? Can someone learning to sew expand their mind and creativity? Or the first farmers testing how to improve production? Questions and resultant answers or acquisition of skills (mind food) do not need to be derived only from philosophy.

This sounds to me like you're doing quite some philosophy yourself here.

I suppose I could have made a carpenter/chair comment.
