That is very true, and indeed if everyone liked exactly the same things this planet would be rather a boring place, would it not?
I am certainly not against the use of sunny weather for the purpose - at a guess the vast majority of my own pictures are from sunny days. My point was that you shouldn't stick to just sunny weather otherwise you'll be missing out on some quite dramatic photo opportunities, so I would certainly encourage you to try in less favourable conditions and see how you get on with it.
Have you ever tried night photography, for example?
