Don't compare yourself to Pace, he's wise because he lived for around 20-30+ years in total (if you'll count his life before his reincarnation).
He's got the looks thanks to his mother's genes.
He got strength and wits thanks to his father, 'the knight Hero's' strict training and he volunteers to be trained at an early age.
His magic was only by chance since it can't be inherited (unless it's predestined which there are no clue as of latest web novel chapters).
You're just fine for your age since Pace is out of common sense and you've got a fine & reliable right hand man who will advice you and help you manage your territory without help from others.
<spoiler>
You'll even grow your territory population from 500 to around 10,000 and have a very thriving maritine trade, with an even a greater influence second to Count Retes.
You'll even get married to an older pretty and smart wife as well and even have a son ahead of Pace (even if Pace gets married earlier than you).
