I found in this hobby (for me) If I was doing stuff without mistakes it was a surprise. Sometimes even straight and level flight was a challenge.

IR training was humbling in that I found that I constantly tried and chased perfection and made every mistake you can make (and still do), and told to not sweat the small stuff about as much as i was “more right rudder” in PPL training. Nothing that would compromise the safety of flight but things (in my mind) that didn’t meet what was assigned. Hand flying approaches, headings, holding altitudes in thermally weather…it takes practice and there are margins. A mistake to me was deviating from what was assigned. Maintain 3000?, I’d bounce between 2900 and 3100. Heading 360? I’d be 350 or 010…look left to brief an approach for a few seconds to see I lost a hundred feet. Not making a no-go call well before starting my IFR oral and later discontinuing due to weather. In hindsight I should have just rescheduled the whole, in the end it was a discontinuance and a pass.

You’re going to make mistakes I’d say almost every time you fly. As you get more experience the margin of those mistakes should shrink but will never be eliminated.

As others have said, they’re all in the same boat from zero timers to 10’s of thousand hour pilots. Mistakes will be made. You learn from them, try not to repeat them but in the end you’re still constantly learning.
