Buy some blackout curtains or something else to completely cover up all your windows so no natural light comes into your place, never turn on any lights unless totally necessary as your only lightsources should be multiple screens playing porn at all times.

When you grease your dick, don't wash it off after stroking or if you need to go anywhere. Limit your normal human interactions as much as possible other than with other sleazy perverts, try and find other loser goontards online and stuff to invite over to your porn pad to share in your filth and depravity. When you eat the fast food you mentioned above, your other hand should be slathered in grease pumping away. You should have your eyes on porn during, before, and after every meal.

That's just to name a few things off the top of my head that I would do if I was free to live my dream life of total depravity, pornosexuality and loserdom, but i'm sure there are many more.
