What to paint?

I have SO MANY photos in my 'to paint' pile.  Every time I see something that looks interesting I take a photo and put it away.  When I start a new picture, I like to have a variety of subjects available, because I never know what will catch my fancy that particular day.
I'm trying to expand my collection of local architecture to include Galt, Preston, Guelph, Kitchener, Puslinch areas.  I try to think of what would be of interest to people......what buildings or places give identity to the community.....what buildings are gone now, but would be nice to remember in a painting.

However, I've been working on several commissions these last few months, so I don't get to pick!  I enjoy being able to do the commission work, because every time it challenges me to paint something that I would not have picked myself.  And that is good!  I recently completed this commission piece which was a gift for a couple getting married today at Ellis Chapel.  They already have my painting of the outside of Ellis Chapel so the gift giver asked for a painting of the interior!  I have never painted the inside of a building before.....but....why not.  You just paint what you see in the photograph.  I'm quite happy with this piece and look forward to maybe picking some other interiors to paint!
