I'll second what most people said: hard work, lots of food, and protein. I would suggest more than 2000 calories. When I was young and a hard gainer 2000 calories is what I normally took in just to stay alive. If I wanted to think about increasing size I had to eat 3000-4000 calories per day. Now that I'm a bit older and my metabolism has slowed slightly I have to eat between 2000-3000 calories to get bigger. I am too cheap to eat that much food so I stay a bit smaller than I would like.
But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new guards for their future security.
Translation for the intellectually challenged: If the government screws the people too much, it is the right and duty of the people to revolt and form a new government.
