In your current state of consciousness, you can't choose your mood. You're not "a master of being." You're not a Zen master yet. It would be better for your mental health to realize that and to simply admit that you're clueless and ignorant. It took me a while to admit that to myself (that I was clueless) and to face my naivete and my irrational behavior. I was a naive person! And I'm still ignorant to a certain extent — sometimes I'm going through phases of irrationality, but the only thing that keeps me sane is the fact that I'm aware of an ego that wants to have its own way; to be out of control. Knowing how to differentiate between thoughts and emotions, and make a separation of them when I need to, such an approach gives me the freedom that leads to total liberation — I am no longer identified with a negative mood. I chose to anchor myself in that which witnesses the negative mood. It is simply an act of observation; we don't have to super complicate things or reject new solutions just because they seem unfamiliar to us. Other than that, we shouldn't take everything for granted or as truth, but rather keep an open mind and embrace new ideas just to see if they would work. You say this: "I don't know if this is true or if this will work — I am only willing to try it. If it works, fine! If it doesn't, that's also fine. At least I tried, failed, and learned what works and what doesn't." And to me, that's the key to rationality. Even scientists are using a similar approach — a lot of times they try bizarre ideas that lead to new discoveries, regardless if a notion seems unfamiliar or ridiculous to them. Be more flexible when it comes to trying new ideas or concepts, and see what happens. Why do we have "truth" and "falsehood?" For the purpose of discerning — it's that simple.
