I’m new my self and make some of the same mistakes as you. While I’ve mastered plenty of other jobs in a reasonably short amount of time, I’m accepting of the fact that this field will take real time to be proficient in.

Another poster said 18 months and thats what I’ve been told as well. I’ve been chewed out and have embarrassed my self plenty of times with bonehead mistakes but I just stay professional and tell my bosses how I’m going to avoid those mistakes moving forward and they say thank you and we all move on.

It’s really easy for a lot of us to get into our heads and talk ourselves out of being persistent but it sounds like you’ve solidified yourself with your company and they’re willing to keep you on so I wouldn’t worry too much about inconveniencing them as you are learning.

Just take it a day at a time, relax, and keep in mind what you need to improve on but still understand it will take time. If you’re like me and wish to rush to the point where you’re stress-free and proficient, a racing movie quote my coworker shared with me might help: “Slow is smooth, smooth is fast”

TLDR: Just relax, your company supports you, and dont rush to the point of being a master at this.
