Hopes and expectations.

Don't have any of those. That's the general advice. Why? Because that way you will not be dissapointed, deceived, your heart will not break, and a lengthly etcetera.
Nevertheless...can that task really be achieved? Aren't humans always trying to achieve some goals, like pleasure, stability, love, success? Isn't it?
I believe so. It's essencially difficult to ignore all the wishes, longings, and drives that everyday make the people wake up, drag themselves upon a cruel world and try, try, try.

I can't expect to not expect.
Although, as always, there's a catch.

You can expect whatever you want, desire everything. But that doesn't mean it will happen. There are always things beyond our power, things that are not going to happen, even if our heart is set upon them.

And that hurts...and will hurt.
