Ah me! how hard a thing it is to say

Change is hard, I should know. I should know.

It is very difficult to be wise (through the mind); it is not difficult to be wise occasionally and by chance, but it is difficult to be wise assiduously and by choice.

It is not easy to conceive the difficulties we have had.

Not knowing it was hard; knowing it was harder

It has not been easy for me

All shall be done, but it may be harder than you think.

You must try harder. It is not easy to become sane.

The difficult is what takes a little time; the impossible is what takes a little longer.

How difficult it is to be simple!

Yes, it's hard to write. But it's harder not to.

I know it seems hard sometimes but remember one thing. Through every dark night, there's a bright day after that. So no matter how hard it get, stick your chest out, keep ya head up.... and handle it.

Simple can be harder than complex. You have to work hard to get your thinking clear enough to make it simple. But it's worth in the end, because once you get there, you can move mountains

The Difficult is that which can be done immediately; the Impossible that which takes a little longer.
