Confession is a hard habit to fall into but the more you do it the easier it gets. After awhile it becomes hard not to confess. If I don't confess for a long period of time (three, four weeks) it takes a serious toll on my attitude.
You should talk as if addressing your confessor, remember, he is the vessel through which God speaks to you in the mystery and that Christ gave him the authority to forgive your sins in His sted. Confession is one of the most tangible moments when we see the priest as a living icon of Christ.
I always write my confession down and have never had a priest tell me not to, just remember not to be scrupulous, that's a sin too.
