I know it does. And it's all fucking magical when
it happens. Feeds on itself, and just keeps getting
better. Ah, there are setbacks, but overall.
But, 'tis not something you can just decide.
It's all in little steps. If you psyche yourself
into some sort of positive attitude, expecting
to succeed (ah, how they always advise this
crap), and you don't - you fall even further.
Aim for little things. Even they may be too
much. But, the cost is less.
