Situations can corral you.  Much like corrals help tame and control spirited horses, situations can alter your behaviour and your thinking. Corralled behaviour and thinking: it can be a very good thing; it can be a very bad thing.

Consider, for example, the situation where you're thinking is corralled into accepting you lead a hectic life and so you are 'too busy'.  If you truly believe you are too busy then you will think and behave like you are too busy. Then the I-am-too-busy mindset becomes your self-confining corral.
