Some are unhappy even though they have everything, some are happy even though they have nothing.
Our happiness is not in our satisfaction but in our ability to feel satisfied.
We can't appreciate what we don't value and when we value the wrong things we can never be happy.
When we value the right things we are happy because even if we have nothing, we have everything.
When we value the wrong things we will always be unhappy because there's never enough of the wrong thing, but we only need a little of the right thing cause the right thing is always enough.
Remember last time you received an amazing gift, or imagine getting something you've been working hard to get. Close your eyes, how did you feel? Were you happy because you "GOT" the thing or because you felt loved/appreciated?
