One thing that is extremely important in life and that is to learn. If you have a dream to make a great game, then do it and on the way learn everything you can. That includes making GDD’s, team management, etc. Read books (a great book is The Art of Game Design)… watch and read tutorials. When you run into negativity and people saying you can’t do this or that, just nod your head and continue. Always stay positive and that will help people assist with your endeavors.
