Anyone else get incredibly mentally exhausted when writing a lot?
Just thought I'd throw this out into the ether as I'm now in bed, very tired, but most of all mentally exhausted. I've written something like 30k words in the last 2 weeks on a run of crazy motivation and inspiration, combined with a touch of discipline, but it's so mentally draining.
I do physical sports and dance and they're also mentally taxing but nowhere near this level of concentration.
Does anyone else feel this when they write a lot in a short period? Not just writing but also planning the next volume as I go, so I'm genuinely exhausted just from thinking and typing things with a keyboard.
I need to know if other people experience this. If so, what helps you keep energised when writing a lot in a short period?
