If you could improve the efficiency of any task in your job by 100x, what would it be?

Ability to learn on the fly. Just in moment learning or the ability to retain and grasp concepts at the moment of problem so that I can get the task done. This is what causes most friction at work. I believe at work the most important things to address in order to improve efficiency are by addressing the time taken while setting up tools or going through software, going through overwhelming documentation, debugging etc.
