I say what I mean.  And I try to do what I believe.  Given human nature, we fall short but we begin again. 

But failing doesn't undercut the idea, it only helps us to see our need for God, it keeps us humble, but it doesn't undercut the truth of some resolution or goal.

God wants us to accept the fact that we are always beginning again with Him.

The more cheerfully and quickly we dust ourselves off and begin again with Him the easier it gets, and the humbler we can become. 

Discouragement and sadness are allies of the devils. 

The devil is always trying to drive a wedge into people (their intellect/conscience, their will, their body, their appetites), and between people.

What you say vs. what you do.

Look at the Pharisee's poking at Jesus about His disciples picking up wheat grains on Sabbath and rubbing them in their hands for eating them.

Driving wedges....declaring hypocrisy. 

Those are his ugly tools.  Don't touch them; they will quickly make a person cynical and bitter.
