I realized that software engineering is not engineering as in applied physics, but more like engineering as in creating things. The opinions of experts are just that, opinions, and there is no need to adopt everything. They are not exactly laws of nature being described. Its ok to have your own opinions and methodologies as long as things work (of course, as an employee I choose to simply follow the herd, but with my own things I am my own person). The best decision I made was adopting this.
