I would not create a separate account for every interest right away. I would first look for the audience overlap: skateboarding, fashion, and overseas lifestyle can fit if the account is clearly about your perspective, while cooking and dog training may feel unrelated unless they support the same personal brand.
A useful test is to define one sentence for who the account is for and what they should expect from following it. Then give the main topic most of the posts for a month, and use the other topics as recurring side pillars. Track follows, profile visits, saves, and comments by pillar, not just views.
Split only when one topic consistently attracts a different audience or makes the rest of the page confusing. Starting with multiple accounts creates a lot more work before you know which ideas actually have traction.
