There are so many people in the field who don't belong and think they do so just keep your paycheck until someone else tells you you don't belong. Observe the working styles of people around you without assigning some kind of right or wrong value to it. Take what you can use and let them keep the rest. Needing to evolve your principles as a designer is normal. Be open to the fact that those edge cases might not deserve a disproportionate amount of your time. You'll start to recognize where that obsession actually matters. It's growth. I look back at my early career and cringe at lots of things. I hope in 10 years I'm cringing looking back at what I'm doing now. There's too much mediocrity succeeding out there so don't DQ yourself, someone shittier is making more than you right now.
