I'm probably of the minority to build around Paragon Path first. After finding one that suits me it helps determine class and race to make the most out of the concept.
For this reason, I consider the racial paragon paths to be the most fun since they don't force a class on you. Too bad there are so few of them that I'm aware of.
This is also fun, as well as starting with epic destinies in mind. I made just such a character recently. I was going to be part of a seafaring campaign (keyword was), so I wanted the paragon path in the Forgotten Realms Player's Guide, Sword Coast Corsair. But the requirement of "any martial class" clashed with my character concept of a human monk. So, I simply took a multiclass ranger feat as my first level feat. Bingo! I can take that path when the time comes, and I can deal 1d6 extra damage each encounter!
