Everything you experience is filtered through your mind. There’s no way to remove this filter, (nor would you want to).
If you want to change your behavior, or how people perceive you, you need to embrace the art of contextualization.
Reading a book, writing regularly, and identifying someone you want to be more like and listening to how they speak (and even transcribing it), are all great ways to recontextualize. The work by Byron Katie is a great exercise to reinterpret or reframe an experience.
When you change your filter, you’ll start noticing different observations. For example, instead of noticing all of the evidence somebody doesn’t want to support you, you may notice some facts that suggest they could be interested in supporting your work. You’ll start self-fulfilling prophecies that lead to outcomes you want. Your attitude will naturally shift to an open, expansive, posture.
Even if you’re interested in a field of work that’s shrinking, or going against market trends, you’ll adopt a new approach or perspective that enables you to keep moving forward.
It’s important to make sure, of course, that there’s evidence and that your context matches closely enough with other people’s contexts.
