take it/life as it comes
When you 'take it as it comes' you deal with situations as they occur without planning ahead. Usually, the choice to 'take things as they come' is because it is impossible to plan ahead for a particular event or because you are the kind of person who prefers to deal with things as you go along. This is a casual expression used in social and professional contexts.
