Extra-curriculars and clubs

Hi!! I'm a junior at a fairly small school (only about 135 total in my grade) and I was wondering about college apps, and how extra-curriculars would look. Is there such a thing as too many? Like, would it seem like I'm trying too hard? lol. I'm thinking of joining DECA, but I'm not sure if I have the time or if that would help my college application at all. I plan to apply to prestigious schools, (I think I have a chance?) I am currently the valedictorian so I'm hoping to keep that rank.

Here is what I have at the moment:

President of the Interact Club (community service)

Goat Showing (FFA)

4 FFA competitions in fall & spring - floriculture went to state last year

FFA officer

Student Council

One Act Play (theater) - (state champion last year)

Jv Tennis

National Honor Society

my time is very taken up in the spring by One Act Play and tennis, so I'm not sure if I should join DECA due to that. I would appreciate any insight! thanks! ⋆·˚ ༘ ੈ✩‧₊˚
