Producer vs. Consumer
Found this insight in Reddit's /r/fitness section, of all places. Read it and let it sink in; make it a habit starting tomorrow. Props to Redditor aceex.
I make sure to start every day as a producer, not a consumer.
When you get up, you may start with a good routine like showering and eating, but as soon as you find yourself with some free time you probably get that urge to check Reddit, open that game you were playing, see what you're missing on Facebook, etc.
Put all of this off until "later". Start your first free moments of the day with thoughts of what you really want to do; those long-term things you're working on, or even the basic stuff you need to do today, like cooking, getting ready for exercise, etc.
This keeps you from falling into the needy consumer mindset. That mindset where you find yourself endlessly surfing Reddit, Facebook, etc. trying to fill a void in yourself, trying to find out what you're missing, but never feeling satisfied.
When you've started your day with doing awesome (not necessarily difficult) things for yourself, these distractions start to feel like a waste of time. You check Facebook just to make sure you're not missing anything important directed at you, but scrolling down and reading random stuff in your feed feels like stepping out into the Disneyland parking lot to listen to what's playing on the car radio - a complete waste of time compared to what you're really doing today.
It sounds subtle, but these are the only days where I find myself getting anything done. I either start my day like this and feel normal and productive, or I look up and realize it's early evening, I haven't accomplished anything and I can't bring myself to focus no matter how hard I want to.
