Is it worthy to start joining orgs?

Hello ! as an 'average' student in the past few school years, I am currently having thoughts of having to try joining orgs (BSMT freshie), but I am somewhat scared since I have zero experiences when it comes to that, like, I've always thought that orgs or being a student leader is not for me as I don't engage in social interactions that much (naturally introverted). Pero deep inside, I want some changes and I thought maybe joining these would be a great start. Is it worth trying?

I'd also appreciate if you suggest some orgs na hindi masyado... you know, loaded, as a BSMT freshie hehe. Thank you!
