Tight-lipped elders used to say, 'It's not what you want in this world, but what you get.' Psychology teaches that you do get what you want if you know what you want and want the right things. You can make a mental blueprint of a desire as you would make a blueprint of a house, and each of us is continually making these blueprints in the general routine of everyday living. If we intend to have friends to dinner, we plan the menu, make a shopping list, decide which food to cook first, and such planning is an essential for any type of meal to be served.
