When we’re driving at night from one place to an other, we don’t need to see the whole road for us to start driving. We only need to see 100 ft (30.5 meters) in front of us.
This sounds a lot like our life. We don’t need to have our life figured out for us to start living it, we just need to know what we’re doing this week, this month, and what we hope to be doing the next 6 month, and off we go.
Dwelling on the past will get us to crash, because you can’t drive looking at the rear view mirror.
We just need the next 100 ft for us to keep going until we get there.
