Jobs at larger, more stable corporations can still take a lot out of you! Even if it pales in comparison to the insanity of startup life.
For myself: the drive, and the creativity, only come back if I stop working for an extended period of time (weeks). I need a lot of idle time and some boredom before I feel creative again, let alone want to touch a keyboard, but if I wait long enough it always happens.
I promise you the creativity and desire is still there. It could be more that the current job (or something else) is suppressing it, and less that you haven’t recovered something you lost.
Boredom is a totally underestimated and undervalued mental state these days. IMO it's quite difficult to become bored these days with all the distractions of the Internet. Many great thinkers went to rural "boredom resorts" to let their ideas thrive after they got stimuli from crowded cities.
I hate it when my precious limited boredom gets intruded on by nagging feelings that I need to learn or achieve something to avoid falling behind. I seldom have the energy/willpower to learn or achieve well anyway, and end up wishing I had enjoyed my boredom instead.
