Is your story more than "I was as mechanically optimized as possible", and again, how would your character even KNOW he had made the best choices possible without knowing he was a character in a game?
My Pathfinder character did not choose to be a kitsune or to be fey-blooded, or probably to some extent a sorcerer at all. But once he discovered that he had the power to bend people's minds to his will, why would he take any other route then doing those things that would maximize that power? If you're going into combat situations, are you not going to choose the best feats to study to make sure you get out alive?
If you saw the character sheet for Simo Häyhä, you'd probably say that he's horribly mechanically optimized. But it turns out that people who become the world's greatest sniper tend to have an obsession with guns, they have the stats needed to become the world's greatest sniper, they tend to be mechanically optimized. The best in the world don't tend to get there by being dilettantes or being natively unsuited for the task.
And lastly, if the DM and the system wants me to be not mechanically optimized, it needs to reward me for that. Yay, you put points into Profession: Midwife! That might actually matter in the game! Not just make me feel like I choose poorly when bad things happen in the game because my character is not optimized enough and enemies get past him to the wizard or he can't deal enough damage to the BBEG.
