Do you think this line "note to self: stop expecting" is true?

I mean, lately I have had more and more experience with just people not keeping their promises and if you want something to be done good, you are gonna have to do it yourself.

And also, if you meet a new person and you think it's all gonna be so cool, but after a while the bubble bursts and you hit the ground again. So you better not raise any expectations.
