Thinking about thinking. Feeling about feeling

Clients asked what are the best ways to tackle anxieties and frustration. I don't know about others. I use "thinking about thinking" and "feeling about feeling" to counter whatever situations where I feel frustrated and confused. These tools instantly give me space that helps evaluating what state of mind I make myself into. " Make myself into frustration and anger" - no joke, we make oursleves miserable and become victim of our own making.
