You need “slack” or a buffer in your system, your schedule, and your life. If your schedule is too tightly packed, when one event runs past it’s allotted time, it will have a domino effect – causing you extra stress and making other people wait on you. When you’re late for one event, then you’ll probably be late for the one after that, and the next one, and the next one…Plan for everything to take a little longer (giving yourself extra time, aka “slack”) and you will reduce stress/anxiety.
This concept can be applied in all areas of life – even thinking of your budget/emergency savings. Instead of stressing about money when an emergency pops up, you’ll be able to dip into your emergency fund to pay for it. Just be sure to replenish it, as another emergency will inevitably occur at some point in life.
