We tend to quickly perceive...
... things we are focusing on, but not things we are not focusing on.
... things we expect to see, but not things we don't expect to see.
... things we want to see, but not things we do not want to see.
Our experiences and perceptions of people and events are therefore shaped by our focus, expectations and wants. If you want to broaden your perceptions, to learn to view things more as they are and not how you want or expect them to be, you need to suspend your beliefs and expectations.
Don't interpret, simply observe. Typically far easier said than done, but it will open you to far richer experiences.
