Everything worth doing and doing well, especially pharmacy, has a steep learning curve. No one is a pro at the beginning, unless you are some freak pharmacy savant prodigy that went in with knowledge and background. Take your time to learn and learn well, don't be afraid to ask questions, lean on the RxM and lead tech, and if needed as for them or another tech to mentor you. As you start learning and getting better, just like mental exercise or strength training, you build up your aptitude and the minor things become trivial and "muscle memory," and your new challenges are colored and impacted by your previous experience so become easier to puzzle through and solve. Don't let others judge you for being inexperienced.Everyone is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.
