One, two, even 5 lab sessions aren't enough to do what you have to do.
There's only one way about it, only one: consistency. Schedule your time in the darkroom and the first thing you know, you've printed all your negatives and it's become addictive. As an example, do it every monday, tuesday and wednesday from 6PM to 9PM and follow religiously.
What you do during those hours in the darkroom can be totally unrelated to printing. Could be listening to a Football game while cutting negatives or choosing what negatives to print. But spend that time in there. Soon enough, you'll have printed everything and you'll be asking for more and it will all seem like a Breeze.
