hi lee, thanks.
i don't know if i am an old pro but i've goofed around a lot doing stuff ( and i set my "personal bar" low )

i think the hardest thing in the world is letting go
and sharing responsibility with the camera.
3 interesting out of 30 sounds good to me

the other 27 are probably interesting too, but maybe you aren't "removed" from the situation enough

to see with eyes that have set the bar low enough that even the biggest
potenial failures could present something beautiful and unintended of epic proportions you might have missed

i can't tell you how many negatives i have that 4 or 16 years later i looked at and was
blown away and mystified at what a thing of amazement i had created. (this also
happens with exposures where i used the eye piece and made exposure and focus controls/calculations
and expressed complete intent/determination for every exposure, like a portrait session ).
the self timer walks i think i chewed up 10 of 20 rolls of film
to get a few interesting images. i eventually stopped when $$ got low.
maybe the person i met has removed himself so far from the instants
that the images magically have transcended from terrible to mccartur fellowship .
