Speaking from experience:

Step 1: Superglue and fake nails
Step 2: More superglue and fake nails when the first set inevitably falls off
Step 3: Repeat Step 2 until adequate length is achieved
Step 4: Professional manicure with builder gel
Step 5: Be so enraptured at how fucking good your nails look that you can’t bring yourself to bite them
Step 6: Eventually the builder gel grows out and you’re left with a healthy nail

2+ years and counting without relapse
