The term laissez-faire describes a policy of leaving things to take their own course without interfering into it.

Laissez-faire is a French term that literally means 'allow to do', or 'let it be'.

For example, if a person has a laissez-faire attitude to life, it means that the person just allows her/his/their own life to take own course as it comes towards it. This also indicates that the person (having an laissez-faire attitude) does not get involved in other people's activities or behaviour either.
