Prefer results and the truth to affiliations
We all have a natural tendency to belong to groups, a tendency that often goes beyond its basic form, creates strong affiliations, and causes problems. We lose a lot more than we gain because of affiliations. We can become more professional and effective experts if we don’t limit our identity and preferences to certain groups.
For example, some practitioners turn their method into a religion and start objecting to everything else. As a true practitioner, you shouldn’t care about those childish or cult-like behaviors, and simply learn about all the existing resources, and use the most appropriate one(s). Even for those systems you don’t use, you can still be inspired by and use the knowledge to enrich your selected method.
