You sound exactly like me lol. Programming has been an interest of mine since I was pretty young too and im 15 now. Id also reccomend c++ to you for a start as far as programming language, everyone says its the standart these days. Just remember its going to take some major devotion if you want to make a good 3d game completly by yourself but Ill probably try if I''m ever that good lol. Good luck.
