I only care about my mood

Once upon a time, I wanted everything.
Want to spend more money,
Want a big, wide house,
Want the most sincere friend,
Want a lifetime of happiness.
That's why you live to be tired.

Now that I am, look away,
What does not belong to me will not be disputed,
I don't care about my feelings.
I don't care what people think,
I only care about my mood.
