"If I need to be at work for 8:15,
when should I start getting ready?"
Shower 15 min → Get dressed 10m
→ Breakfast 15m → Drive 35m
We do the backwards math.
So you don't have to.
When do you need
to be ready?
Think of tomorrow morning
You already do this in your head.
Every single morning.
The Old Way
"I need to be ready by 8:15..."
"35 min drive, so leave by 7:40..."
"15 min breakfast, start at 7:25..."
"10 min to get dressed, start at 7:15..."
"20 min to shower, start at 6:55..."
