I've always had a side project going for the last few years. Whether it was a blog, a bit of code or some writing, there's always been something there for me to do. The reason why wasn't really clear to me until I read this:
The Grind is the problem that you beat yourself up over solving every single day. It’s the job you’re in, or the business you’re building. The Grind gets our best hours, our fullest attention, and the whole of our willpower.
Which leads me to the this question: If the company or organisation you work for allowed a percentage of time to work on side projects, would the grind become less of a grind?
