How long does it take to learn photography?

I will use a fool camera for about an hour, use a professional camera to shift gears automatically, use a professional camera to shift gears semi-automatically for about a day, and use a professional camera to shift gears manually for about a month. I will understand the meaning of photography for at least one year and use it to make ends meet and cheat money for more than one year. I feel that I know photography for at least five or eight years.
