I think its simple really, through grand line to new world he didnt run from any fights thats probably Shanks way of pirate life He prolly got this from Roger, and his knowledge about haki he probably saw it from Roger too from his fights. No body teached him no body made him strong its all from his experiences.
So just imagine how strong Roger now on his prime?
So yeah through experiences he improve his strength, agility, and his spirit.. as well his crew did from their fights
prolly during his adventure the sea was full of stronger enemies than the time of Luffy, Shanks probably the one who beated all of them.
