One of the most important concepts to be aware of is the difference between motion and action.
Often we can feel a sense of fulfillment from being "busy". We've been in motion all day, so we must have acheived a lot... right?
Unfortunately, this isn't always the case.
There is a big difference between being busy and being productive, and often distraction or perfectionism stand between the two.
If you spend a large portion of the day ticking off easy tasks that didn't really need to get done, you may be in motion, but you've taken little meaningful action.
If you spend an extended period of time organising or planning, again you're in motion, but yet to take action.
If you re-touch and perfect a task over and over and over again without moving on, once again... you're replacing what could be action, with excessive motion.
To give you a frank example: Let's say you're in a 100m race, and once the gun goes off you turn around and run in the other direction - it doesn't matter how fast you're running, you won't win.
Likewise, if you take 10 steps sideways you are moving, but no closer to the destination.
Know the difference between being busy and being productive, and take what can sometimes be the tougher step forward in a productive direction.
