Great! This is so natural.

When will I finally learn to continue thinking after finding the first
solution, especially when I feel it's not ideal?!

Do you also have this experience with Haskell?: when you feel that
some code is not ideal, almost always it can be improved.

It's much harder in some other languages, for example, in C++ there
is always something wrong with the code ;-)
