Just got a good question. I write, "If you get off track, go back to the fundamentals." I just got asked what they are.
Here's the first things that come to mind -
*Drink lots of water
*Enough high quality sleep
*Not too much sleep
*Eat fruits and vegetables
*Scale back on any intoxicants
*Spend time in nature
*Spend time with people you respect
*Read books you enjoy
*Think/plan on what your goals are
*Some light moving around/exercise (even just a walk)
*Clean up your environment a little
*Get small, achievable wins
I'm sure I'm missing a few. Please add yours. If you do find yourself stuck in a rut, I'd re-visit this list to see what you're not doing, and add some of this stuff. I think it's pretty much the way. Add your additions in the comments please.
Edit - a couple good ones in the comments:
*Resolve to do something about your major goal every day, even if it’s something little. - from Oscar Del Ben
*Take care of the biggest “ugh field” you might have, like cleaning up your desk or computer - from Rafael Santos.
