Turning 21 next month, should I start preparing for my future, enjoy life in the moment, or try new things l've never done before?

I feel like I'm at that age where I want to try everything but at the same time very anxious about my future. I'll be graduating next year, I'll take the board exam, I'll start working. I grew up introvert and sheltered so I feel like I want to take this as an opportunity too to try a lot of things especially that I'm growing my confidence. Likeee it's so confusing 😭 And also I want to build my skills and prepare myself for the real world, I want yo know everything, but at the same time make up for the fun things teenage me didn't have a chance to do.
