I told him that the difference between a self-imposed deadline on personal issues and a court-imposed deadline on work issues, is that, with the latter, you miss it and you get a p!ssed off judge and a p!ssed off boss. With the former, you miss it and just end up feeling more crappy about what a loser you are.
I have issues with procrastination and conflict avoidance myself. Learning to deal with self-imposed deadlines has been something I've really had to come to grips with being self-employed. Here's a sort of trick I learned to deal with my inner brat and/or wimp. Put "improving sex life" in sort of mental category box labeled either "Self-Improvement" or "Relationship-Improvement". Come up with a list of several other things that would fit under that category like "Get in shape." , "Learn to speak Spanish.", "Spend quality time with my sons.","Resolve conflict with mother." whatever might be a real goal for you. Then block out chunks of time on your calendar to spend addressing your choice of any of those issues. So that way even if you feel wimpy or rebellious about dealing with one issue you will get some work done on another issue and still end up feeling better about yourself then if you had just done nothing. It will help you to get a calmer perspective on your sex problem too if you aren't viewing it as THE PROBLEM.
