Seems the way to get stars is by doing something for them. I believe Ashley is the only one you can get stars from in the current version so far.
The mom collect hearts
Veronica only gives stress right now
Ashley - Think I got a star by helping her do homework.
Online classes only goto 15.
off the top of my head...
The thing is Ashley's homework is only at 1600-1700. any time past 1700 is too late and shes on the phone. Dinner is soon afterwards. This conflicts with working at the pizzeria for income. This place opens after 1200 or 1300. The main thing is to hit dinner on weekdays and weekends with the family.
A typical day in my game -
...Sleep with boxers =

or :extremelyhappy: - locked stats for about 6+ hours
(with the bed you start with, sleeping naked might put you in :'()
::|: status with Tired - Food - hygiene - stress not locked (Sleep with relatively fresh locks and high stats)
- Bath
- go downstairs to kitchen
- Eat breakfast

status before 0900
from here I max out or get higher stats for a work day
- my Room to play 30min of *Upgraded Game
- Wash face
- Drink Coffee on the way out

status - leaving
- walk to store
- buy stuff (I didn't do smoking... still need to use the deodorant to see what it really does)
- Walk home

status - Lunchtime before 1300
- kitchen - eat lunch
- drink coffee on the way out
- Walk to pizzeria
- Work 3 hours
Here I am able to manage 2 shifts, and a possible 3rd one if I don't care about dinner.
As you can see 1 shift, will put you too close to 1600 homework time.
- Ride home.
- (if 2 shifts were worked, I take the one that'll have me make it in time for dinner)
::|: status after the work

Status for the evening
This is enough for movie time and pretty much takes care of stress.
IF I want to

, I need to consume items from the store. The bathroom is pretty much occupied for the afternoon to the evening. Usually, coffee + energy drink from kitchen does the MAX Mood for me.
then, do the evening events.
Sleep.
On weekends, I work a ton for the income and use store food + *Upgraded sandwich at home to tide me down through the day.
