THE SECOND WAY IS :

1. Confront your problem. Get a camera and take some pictures of your bitten fingernails. Examine your nails, and list their problems.
2. Visualize yourself with healthy nails, and how great they will look.
3. Pick at least one nail to "protect" at a time.
   
   
   • After a few days, an non-bitten nail will flourish and reward you. Do not bite it. If you must, bite one of the 'unprotected' ones. Sometimes it elps knowing that you have another nail to bite, even if you don't actually nibble at any unprotected ones.
   • Once you have grown your non-bitten nail for a while, start protecting another one. And another. And another, until every single nail is protected.
4. Record your progress in a notebook or photo album. Take "before and after" photos of your nails and put them in the book to keep you motivated. Recognizing that it usually takes three weeks to grow nails half a centimeter, chart out in the book how long you want your nails to be by a certain date.
   • • Example : Today I began protecting my index finger on my right hand. I am now protecting 4 fingers. I almost bit my nails when I was in maths period with Mr. McKenzie droning on about square roots. I played with a bit of playdough under my desk to stop it. My nails are 1.4 cm long and I want my nails to be at 1.7 cm on March the 5th.
5. Eat calcium and magnesium - rich foods so that your nails will repair and grow well. Not only that, but most of the reason that the human body wants to bite nails is the lack of calcium and magnesium in the body and the body needs that material back.
6. Push your cuticles back. Many nail-biters do not have "moons" on the base of their fingernails because their cuticles have not been pushed back. To do this, gently push your cuticles towards your finger to reveal more of your nail. This is easier to do after a shower when your hands and nails are wet. This makes the nail appear longer, and it gives a more attractive shape, which might also be a motivation to stop biting.
7. Find a habit to take the place of nail biting. Whenever you have the urge to bite, do that instead. Some people like to drum their fingers, or just stare at their hands. Just make sure it's not a bad habit; choose a helpful one or one that doesn't really matter either way. 'Bitrex' is a chemical that is put in products to make them taste foul, obtained from your local pharmacy. It's included in nibble inhibitors that you paint on to your nails. Carry some with you at all times. Apply your nasty solution several times a day. If you get used to the taste, choose another brand.
8. Distract your mouth. Eat carrot sticks to keep you busy. Keep a stick of gum handy for those weak moments.
9. 

   No more idle hands..
   Distract your hands by taking up a hobby.
   • A hobby to distract your hands might be making models or maintaining your house, knitting or crochet, running or other outside pursuits, or even nail care and decoration!
   • For those whose nail biting is obsessive/compulsive it may help to approach your hobby obsessively.
10. Cover your nails. For females, fit artificial nails. They can really help. For guys, polish them and apply some shine/growth promoter or petroleum jelly. It's harder to bite nails that are looking great!
    
    
    • Keep gloves in your back pocket and wear them when you want to bite.
11. If you have any surplus growth, cut your nails back. Keep clippers with you at all times. You can't bite if there's nothing there!
12. Speaking about your nails will help to focus your mind on your goals. Ask for help from your partner(s). Keep talking about your goals.
    
    
    • Show off your improved nails', and get much-needed encouragement and praise from your peers.
13. Be proud of your improving nails. They will shine with beauty.
14. Go for a manicure, and chat with the manicurist about having great nails.
    
    
    • If you are male and you go in for a manicure and anyone gives you grief for not being manly, just say you are taking radical steps, whatever it takes. That should be manly enough for anyone.
      
      
15. Keep looking after your nails, with cuticle oil, shine and growth promoter, and no biting!

The positive reinforcement is to look pretty with the nail polisher ....

The negative reinforcement is bitter taste form the nail polish

The positive punishment is i could eat my favorite chocolate if i don't bite my nail in a day....

The negative punishment is cant watch tv for a day if i bite my nails that day

i chose this method because i love my nails to look pretty ( with nail polish and etc. ), and that is actually the reason why i want to stop biting my finger nails....

i would use fixed ratio for this method because every second response is reinforced....
