How do i become a Shakespearean actor?

For a bit of context, I'm 15, and I've loved Shakespeare since I was about 10. I never had a real desire to be a Shakespearean / classically trained actor until I saw Hamlet live a few years ago. Ever since then I've really wanted to choose Shakespearean acting as my career path (I originally wanted to be a costume / set designer for theatre), but I don't know where to even start.

I have extended knowledge on the Elizabethan and Jacobean eras and I've read almost all of Shakespeare's plays. I've memorised a lot of scenes from many of his plays just for fun - I know ALL of Horatio's lines off by heart and I can recite most of Hamlet's soliloquy's.

I'm genuinely such a big fan of Shakespeare and I really want to get into acting but I'm afraid I'm too old to even try and start. Idk if this would even be a problem, but I already picked my A-Levels (textiles, fine art, and classical civ) and they obviously have NOTHING to do with acting. Should I just stick with my original career plan of costume / set designing, or is it not too late to switch paths?

Does anyone have any advice 😭
