1. You check the weather before getting dressed. And actually dress according to the weather.
2. You do your own taxes.
3. Lipstick and perfume make all the difference, instead of being just for dress-up.
4. You actually have a biological bedtime that won’t fight with you (ie, no more staying out all night, not because you don’t want to but because you physically can’t).
5. You watch the news. On purpose.
