Can't make money because of procrastination

I'm sick with procrastination. It's been around for a long time, and it's really interfering with my life. Don't think I'm a slacker. My colleagues say that I know how to work, solving the most difficult cases out of the box. There is a lot of evidence of this. But! It takes me a long time to collect my thoughts. There is a long period between the time I receive an assignment from a client and the time I start to execute it. I lie on the couch all day, sleeping. I can play computer games. I can drink alcohol and then sleep. All the while, in my head, I am thinking about the very difficult tasks that are set before me. I'm almost like "Agent 007" whose assignments are difficult. You think I go in three days to solve a problem? No. I still have procrastination. I hate myself for it. I have no fear. I often know what to do. But the transition from thought to activity is very tight. If you scold me and force me to do something, it doesn't work. Talking me into it doesn't work. There has to be a period of time, and then the day comes when I realize I can't do it anymore. I can't be greedy anymore. And I jump up and run to do everything at stinging speed. These days, my clients are usually just burning up my nerves. They only forgive me if they know I'm professional. my wife is ready to kill me with a look these days. She works strictly according to a schedule and reminds me of a robot, doing and doing. But now she hardly ever swears at me anymore, as it is useless. she just politely reminds me of my clients. My procrastination is really hindering my earnings. I can have few clients because of it. What do I do about procrastination? I don't know. I invented the idea of tuning in to work by playing on the computer. I end up playing for 6 hours, then I go to bed, and then I can work early in the morning. it doesn't always help.
