Gifts come in various forms and it doesn't sound like a habit as much as a unique gift. What matters most is balancing all such gifts so that the child enjoys a balanced life without feeling they're odd, wierd or under pressure to perform. The most gifted child is still a child - their emotions reflect their chronological age even if they're unusually wise or were born with genius intelligence. The thing parents need to be most aware of is such children can get bored when not allowed to learn according to their true capacity.
Depending on your child's age you may want to have him tested for intelligence quotient [IQ] so he's appropriately educated with others more like him than different. Keeping him interested with his studies can be a monumental challenge. However, he'll need social interaction with others his age, including those with similar intelligence. Montessori schools have served those in my family quite well for children learn to be as they are, where they are intellectually, while learning to socialize well with peers.
What you're observing with your child is a unique way his brain is wired - somewhat different from how others' brains may function. If he really thinks it's a problem that could affect his self esteem in a negative way. Others may think he's odd, wierd or strange when he isn't [in my experience]. He simply has a gift not all may understand. Those exist who'd understand perfectly, having a similar gift even if using it differently. He needs to know he's not alone - which can happen when isolated from others like him. Sharing with similar children and good educators is important to his well-being.
Children are remarkably resilient yet the highly gifted often shut down and stifle their abilities - they'll stifle simply to belong. It's their emotional need to fit in. They don't want to feel different and it can be a chore to find others more like them than different. That's why knowing what your challenge is can be so important. Gifted children often learn differently. Some are "wired" differently. To find suitable educators is best done early on. I've found advanced learning summer camps especially helpful with my own.
