how do i pick between production designer & film director

im 15 and i love visual aesthetics within film. ive read the requirements of both production designers and filmmakers, but the issue is i don't know which i match more as the physical and digital artmaking aspect of PD's is something that may be draining for me, but the working under pressure and basically determining a films success based on managing skills is also a challenge for me if i chose directing. i am willing to grow and learn to excel in the end, but which suits me better if within film i immensely appreciate the visuals, fashion, lighting and the emotions/philosophy brought from the specific niche of films i enjoy?
