promises

What do u think about promises?
To me, personally i think it is the uniquely
human way of ordering the future,
making it predictable and reliable to the
extent that this is humanly possible.
Promises is really easy to make but hard to deliver.
Am i right? Times changed and people changed.
We wil never know whats gonna happen tomorrow.
Our mind our feelings our thought can easily changed
especially for those who has no principes in their lifes.
So, think before u make promises and if u did then
deliver ur promises sincerely n stick with ur principes.
