Author of quotes: Alexander Evgenievich Goryunov

If you're not in perfect health, you can maintain it, but you'll always have physical limitations, no matter how you exercise. But if you don't have a perfect mind, you can train and constantly feed it with new knowledge. If you stop training the brain, then you limit your capabilities.

If you just spend money on the game and don't make any money from it, you are not only wasting money, but also time.
