Definitely appreciating failure (in general), is a great one. 

Many see failure or the investment of time as a big red untouchable button, but for me also it’s really important to smash that button over and over.

My struggle is wanting to tinker with too many things at once.. and spreading myself so thinly it is hard to get any depth or expertise in one area. Hence the question

How do you get out of your comfort zone?

You need to be OK with wasting your efforts _doing things you don't know how to do_.

think _"I tried it and I don't need to do it again"_ 
or _"What a great outcome from such a small effort"_.
