Be Absolutely Silent

This article will teach you on how to be completely silent, absolutely dead silent when doing anything, as silent as a Be a Social Ninja.

Steps

Listen closely to every sound you make. Be aware of your surroundings and how they will act when you come in contact with them. If you are trying to walk silently, you don't want any floorboards creaking or twigs snapping.
Practice a lot. You must learn how to blend in with the surrounding sounds.
Have confidence in yourself. The moment you get scared you will fail.
Wear clothes that don't rustle. If you are sneaking around in the house and you have wood floor boards, wear two pairs of socks.
Make sure that the person doesn't know you trying to sneak on them.

Practice on a squeaky chair. Sit on the chair then try to get up without making a sound.
Try not to swallow saliva when too near a person as you may create a "gulping" sound, revealing your location.
Try to breathe through your mouth because you can inhale more air with less sound and time, breathing through the nose is a lot better if you're in one place, such as hiding, because you inhale less air, thus making less sound!
When sneaking, walk on the balls of your feet, gently putting each one down and slowly rolling your foot till it is flat.
Don't get complacent, even after lots of practice.
Practice sneaking up on animals. They are extremely sensitive to sounds, so if you can sneak up on a cat or dog, you know your training is almost complete.
Try not to breathe heavily. Also, avoid panting.
If it is impossible for you to be silent, set up or make lots of noises to distract your target, like throwing small things or turning up the air conditioning so that it is loud.
If you feel as if you are going to reveal your location because of a sneeze, look up, pinch the bridge of your nose, and press your tongue against the roof of your mouth.

Some people will react angrily or violently, so try not to scare anyone who you think might retaliate.
Someone might call the police if you are stalking them.
If you can hear yourself, then the person or animal that you are sneaking up on can hear you too, so be careful.
The same goes for animals, make sure it's one that knows you, and won't attack you if it hears you sneaking up behind it.
Do not do this for any crime.
