The Word says that for those that believe, we are the light of the world, the salt of the earth. Once establishing that, we are to seek the Kingdom of God and His righteousness and all of these things will be added unto you - for it is written. It is also written that the Kingdom of God is not meat and drink but joy and peace in the Holy Spirit.
So the answer is then, whatever that gives you joy must also give peace. Both must be on operation.
