"You don't set out to build a wall. You don't say 'I'm going to build the biggest, baddest, greatest wall that's ever been built.' You don't start there. You say, 'I'm going to lay this brick as perfectly as a brick can be laid.' You do that every single day... and soon you have a wall."
-Will Smith
This is perfect. How many times do we hear "just take it one day at a time"? Here is the little bit of insight that I would like to add to this: If we start laying these bricks without any sort of plan or end goal, we don't know what will come out. But if we only dwell on that end goal and not think about laying each brick, or living each day, our final outcome will be greatly disappointing. So briefly look ahead, make sure you are heading in the right direction, then refocus your attention on what you are doing each and every day. Best of luck!
