Realistic Realistic...?

Realistic...? - realistic

I consider myself pessimistic for realistic limit.
I know that this is not as "healthy", but ...
... it is better to see things as they prepared for the worst and calming of the thoughts that surrounded his "Getting Better", although it is not.
Is not that exactly how the setup for more disappointment?

These are a few things that I have never met ... Maybe It's Me realistic. Who for their opinion.
