Pursue confidence, not comfort.
There’s this idea that once you feel good about your writing tools, you’ll be able to use them more effectively. This is precisely backwards, and stupid. Once you get some experience working with a tool, you recognize what it is and isn’t, what it can and can’t do — and you feel good about knowing what’s up. Bringing your perceptions in line with reality feels good, and creates a sense of confidence (which is what people who look for ‘comfort’ actually need, much of the time).
Seek confidence, not comfort; begin by learning about your world, e.g. tasks and tools. Nothing is as comforting as realism.
