Make a decision to not be content with only being happy.
Happiness is being satisfied only when things are going "good". What about when things are not going so good?
Seek God's inner peace. Let his peace control you and transform you.
Allow it to help you keep the peace within despite of what's going on without.
Like any other good thing in life, inner peace takes a conscious effort.
Bring it. Keep it. Make it...peace.
