If i were not destined to be a fighter, i would try to be a shipwright and go to water 7 to learn from the best. If there's an interesting pirates group ask me to join their crew as their shipwright, i would go and not miss any chance to travel. I would build them my own version Sunny-go and travel with them lol. While in the ship travelling around, i would try learning archery. And if by chance we arrive at wano, i would learn bladesmith skills from wano's bladesmith and made my own katana.
If i were destined to have great fighting talent (like luffy or zoro talent) and not having dumb brain (usopp's brain is fine), i would choose to begin my life like zoro did. Go everywhere i want and gaining money from hunting one with bounty to eat a food atleast. Difference is i would be more wise in saving my money, unlike zoro who just give the whole body of the hunted man lol, and i wont be as bad bas zoro in direction lol. But one day i realize i want to travel the seas to seek what lies beyond my home-island. So when i found a library, i would go there and read anything necessary for my grand journey travelling the seas, for example learning about navigation, very basic medicine, very basic knowledge about shipwright, and cooking skills. Once i feel it's enough, i would buy a ship with the money i collect from hunting wanted men. Well literally i would go to live like zoro did at beginning before sail out, and live like mihawk after sail out for the first time
