Motivation and discipline are mysterious forces that we often try to draw upon to achieve desirable outcomes. I think everyone can relate to resorting to motivational speeches to try and drum up the energy to get to work.
However, something that I've been recently experimenting with is eliminating the idea of motivation and discipline from my life. I was reading this article published by Kelly McGonigal (Stanford professor) who describes willpower as a muscle, in that the more we use our willpower as a driving force for action, the more that muscle fatigues.
What I've been focusing on is creating systems that make work easy, so that being productive doesn't require me to draw upon my willpower. An example of this is using a cheap alarm clock rather than my phone (which inevitably leads to me having my phone in my hands which requires willpower to prevent me from using my phone first thing in the morning).
To leave you with an interesting idea - The most disciplined people are those who have to use their discipline the least
