If you want to be creative, be smart and well-informed. Being alone is primarily important for avoiding interruptions which destroy your train of thought. Being creative requires combining ideas: well, you can't combine them if you have never heard of them. So learn a lot! And learn good facts and proper scientific (ie disprovable) theories, not stupid, useless opinions and religious/political beliefs invented by overblown authorities. Learn everything and believe nothing. Then go create.
