Take a look at this TED talk. It’s 11 minutes well spent if you’re interested in learning or making any improvement in the things that you care about or the way you do things.
In his talk, Eduardo Briceno explains why performance plateaus even when someone is trying their best to do better. It’s likely because they’re in the wrong state. We’re all so used to trying to perform; it’s sometimes hard to remember to be truly deliberate in learning a new skill. That is, having the discipline to make specific time for learning and identifying the key skills, behaviour or technique to work on. The idea of creating a low stakes environment where you can practice without fear is essential.
Find somewhere or someone who represents a learning zone for you to deliberately practice your identified improvement, and carve out specific time to make it happen.
