In spite of emotional turbulence, where does happiness come from?

1 - Knowing that people care about you

2 - Looking over the past and realising the truth*

3 - Looking towards the future

4 - Knowing that, even though you might be afraid, you have the support of family

* (The asterisk on number two: Vladimir Nabokov 'Transparent things through which the past shines!'). It's that quote that means so much right now.
