$10k a day but you cannot talk

You will receive $10k straight to your bank account for every day you do not speak. But you must set a date in the future and if you do not get to it then you must return all the money

Rules:

• No language or any form of communication can come from your mouth

• you may write stuff down and show others

• no text to speech

• you have the capability of speaking but you must not, so if you get hurt you have to resist swearing etc

• hand gestures are allowed

• you can not move your lips to try and have people read your lips

• even if you are alone you may not speak

How long do you last?

Edit: if you talk in your sleep you may tape your mouth
