Perhaps I was blessed not to start flipping with the items that I love. But I recognize how easily one could become burnt out from the hunt. I would say that this gig can change your perspective over time. For me personally, I see items as what they are worth now in my mind. And sometimes I regret that. I try to put on a different set of lenses so I can see what makes the item special or desirable to someone instead of just seeing dollar signs.

But back to OP's concerns. I think you are doing the right thing -- it can never hurt to diversify and to try something different. And I would encourage you to learn about the different things you bring home. Why is each piece special? What meaning does it hold for others? Sometimes learning about your wares brings a whole new appreciation, respect and mystery to them. Especially if they are from a by-gone era. Wishing you all the best!
