When deciding if you want to do willomancy it's very good to keep in mind that your headmate may not turn out how you imagine them, i have willogenic headmates who i made with the purpose to be happy who have become sad & angry. You are making a person, who can have their own feelings.
Your headmate is also not magical, if you don't know math & you willo someone to do math they will only be as skilled as your knowledge goes, you cannot willo a headmate who knows a language you do not know, this also goes for coping skills, if you don't know how to cope you cannot willo a headmate who knows coping mechanism you do not know, but you may be able to willo someone who has more interest in learning things.
Willomancy is awesome, but it's not a magical solution to anything, having a headmate is having the responsibility of sharing a body with another person, who has their own likes, dislikes, & feelings.
