Can only do this if able to build up a state of flow around it. Start small, as small as possible. Not everything good has to be big.

All the comments like "dump everything and dive in head first for X months" sound like some weird cult of extreme heroism to me.

Everything is a process, not some abstract form that can magically be reified into existence by wanting/trying harder. We are animals and have to build up the habit and curiosity in tandem, else risk burnout.
