Be careful and THINK about what you are doing. Consider each and every shot you take might be THE best shot you ever made. Get familiar with one or two films and only one developer, and only one paper and developer. Use a graded paper and make your negatives work for that one paper. Never rely on " I can make up for shortcomings with ___" (fill in the blank). Never be rushed, take as much time as you want and need, whether shooting or printing. When processing or printing, have one established routine and never deviate from it.
