Don't forget you have no "real" persona. If you play a "role", it means at least a part of you is that "role". If you ditch the open part of you for the hidden one, you will not feel better.
I'd say, try to find a compromise between the two. Build an outlet for impulsiveness in your daily life. Try to use these bursts to propel yourself and reach goals you sincerely believe in. Don't think too much.
