If you have the budget to have an office I think it's generally a smart idea, but for myself I work in my bedroom and have yet to lose my mind. It's one of those "life is what you make of it", or I may be a freak because I like working 14 hours a day and having no life. So I guess in general having an office space is a good idea, but if it's not within your budget, you can still make it work.
