part of my workflow i want to improve?

in general, take more time to get to know better the technologies and tools i'm working with.
e.g. learn all the fancy hacks and features of my IDE or of a certain language or framework.

i tend to be in the mode "i don't have time for that, it already works the way i use it". if i spend "too much" time on learning stuff, i feel bad, since i could also spend that time working on my ever growing list of tasks. but i think, that's not a good habit...
