Think we're a very similar bunch here.

I do it because I enjoy it.

If I have a photo that I think is nice enough to put on the wall for a while - great!

Although I don't try to capture a moment (either to record it, or remind me of it) at the time of taking, looking back through the results generally reminds me of the time/place and evokes pleasant memories.

If someone else has done something similar, good for them, but does that really matter?

He's a pro, totally different ball game, he has to work for different masters in order to make a living. I do that in the day job as well, it's necessary to pay the bills and keep a roof over my head - and to be able to buy the camera kit

My photography however is done for me, and as long as I'm enjoying it why does he think I'd care what he thinks?
