HOW are people getting a week out of a mani?

At this point I'm baffled. It's been years. I've figured out how to strengthen my nails and they're hard as rocks. I moisturize them regularly. They rarely break. I shape them with a glass file. I've tried every base coat and top coat under the sun. I clean them with alcohol before applying polish. I wrap my tips. I wear gloves when I cook and do dishes.

Gel doesn't even last. My girlfriend has a UV lamp and gel polishes, I did my nails Friday afternoon and my right middle finger is already lifting at the tip.

The max time I've ever gotten out of a mani is 3 days, and that's rare. I don't get it. What am I missing???
