Yes. I think the sentence would flow better if you removed the word "some" after learn. Using the word some twice in the same sentence is repetitive.

"Some activities are very creative and they give me good ideas." "learn an idea" is odd. "acts" is odd here. I recommend using the "so...that" conjunction in situations which are more specific than yours. e.g. "I watched a film last night that was so funny that I ached with laughter!"

Maybe using the word "actors" is better.
