Hi bershka,
and welcome to the sabian symbols. I love your avatar btw, it's so calming and peaceful.
I don't think I've ever drawn this card for myself, or in a reading for someone else either. But, that doesn't stop me from discussing it

lol.
I believe how you see this card will depend on how you see the ocean in general. Sure, this symbol is about the white caps on the ocean, and, you don't normally get white caps on a calm day.
So, inherent in the symbol's title is choppy conditions but even so, it would then depend on your vantage or viewing point of this ocean as to how it reflects you.
For example, what if you are in a beautiful mansion, high on a cliff-top, overlooking this ocean. You are safe, and warm, and simply look at the ocean's movement with wonder. Realistically, viewing a choppy ocean is going to be more exciting than viewing a calm one, as there is much more activity.
I guess what I am saying is that with the symbols, sometimes you have to look a little deeper and visualise what the symbol actually means to you.
If you prefer a slightly-choppy to a calm sea, then, there will be no nervousness associated with this symbol. It's all a matter of your perspective.
with love
