Your life should be like a sandwich. The more you put in it, the more interesting and savoury it is. But if you do not think while putting it together, and just stuff into it everything you find within your reach, it will be inedible, regardless of how colourful its ingredients are.
You have no limits in your life except the ones you have imposed on yourself. So, let your life be like a sandwich, a big one, the biggest one, but with carefully selected ingredients.
