How long does it take for something to become a habit?

Answer

Every person is diffrent. So, it can take diffrent amounts of time to grow on and off a habit for diffrent people. It also depends on what the habit is.

Although your question is too general to offer much help, you may find this interesting to observe regarding creating or changing "habits".
Simple repetitive tasks require a timeframe of approximately 21 days to condition.
Here is a familiar example: When you walk into your bedroom you "automatically" reach for the light switch on the left side as you enter. Then you move to a new home where the light switch is located on the right side as you enter. You will find that it will take you about 21 days to stop reaching for that light switch on the left side. (that is not there!). You will also find this 21 day "benchmark" to be the time your new house will start feeling "like home".

Answer: Around 30 - 40 repetitions, with most people.
