Why do CFL energy efficient 15watt bulbs not last as long as a normal bulb?

I'm always hearing about these stupid spiral bulbs that supposed to last 3-5 years, but I use them all the time and theyre always burning out, and if Im working on my artwork they just dont get bright enough, Or if you walk into the bathroom you could stubb your toe on something because the light has to like charge for a second before it comes on. I think they would be good for outside street lamps or something that runs all day long, but indoors they suck. What do you think?
Oh and I have 3 in my living room ceiling fan right now because thats how many it takes to light up the room. which is 15x3=45 watts total or 1x 45 watt bulb that will last longer and is lower priced.

I have some that have lasted for over 20 years. Not used that much, but when they are, they stay on for long periods of time, like they are supposed to. An ordinary bulb would be better for the bathroom or fridge or anywhere the light will be turned on and off frequently. For any lights that are left on for long periods of time and doesn't use a dimmer a CFL would most likely be better. I've never found they burn out faster than the incandescent ones when used as they were designed for.
