The key to development is deliberate (ie mindful) practice 

In his book "Peak" Karl Anders Ericsson differentiates (unthinking) habitual repetition, which strengthens existing ways of doing things, from (mindful) deliberate practice, which allows you to change, to improve, and to learn new things. I use PERFECT as a mnemonic to capture his ideas.


PE = Playful Environment - Step outside your habitual routine to create a safe / non critical context, in which you can play around with different ways of doing things WITHOUT anxiety. If there is anxiety (fear), habit will kick in and stop you being creative or trying new things.  

R = Representation - Guide your exploration using a mental picture of what you are trying to achieve - what it looks like, feels like, or allows you to do. This may come from a coach / mentor. 

F = Feedback - Use self observation to review objectively (ie without criticism) what happens, in order to refine your ongoing exploration. Others' observations may help in this. 

EC = Experiment Checklist - From your successful experiments, identify one or two specific thoughts / images / areas of focus which help you achieve your goal. Use these to apply back in real / normal situations - until your new approach is a new habit, and you no longer need them. 

T = Trigger - Allow events to stimulate your curiosity and re-inspire you to start playfully exploring again. Or be inspired by the different perspective, knowledge or skill of a coach / mentor.
