Not unless improving some of my skills is.
Natually I choose not to borrow the genius of someone who is not demonstrating a genius skill.
Also remember you're an observer. An observer does not take what does not belong to them but learns how it's done so they can develop their own skills.
When you step into someone with the borrowed genius technique you stay the observer. You don't try to become them. You observe how they think, how they feel so you can learn what you need to do yourself.
If you step into someone to take on their personality well that could lead to trouble. Psychics often have the problem of seperating their feelings from the person they are connected with They don't even need to enter the body so when they "go into" a person they take on even more.
Remember you're an observer to learn.
