Is there a way to make Dashing Diva last longer?

I just got into the office and was about to change into comfortable shoes when I noticed that one of the Dashing Diva stickers on my right big toe is gone.

I wonder if it's somewhere on Line 4... My other toenails are small, so it wouldn't be noticeable if they fell off, but since this is my big toe, it really stands out, so I peeled off the ones on my left toenail too... It's a bit embarrassing having bare toenails... Others say they stay on for a week without a hitch, but I don't know why they can't last more than a few days for me when I get pedicures ㅠㅠㅠ I put them on over the weekend... and they only lasted 3 days... Is there any secret to making nail tips stay on for a long time?
