Erm... lots of water. I drink at least 2 litres of water
everyday. Lots of fruits and vegetables too, especially apple.
Minimal exercise daily.
Try to sleep before or between 10 pm - 2 am in order to maintain
good complexion. That's the period when your skin cells regenerate.
This is the only habit I can't pick up... as you can see from the
time I posted this...
And, constantly keep your mind off-stress and stay happy. Hard to
achieve huh? Especially right here in Singapore, where everything
is so pacey.
