When you spend all day at work distracted by things you want to work on or try in your project and then by the time you get home, you are too mentally tired to concentrate so you just browse the forum instead and think of more things you won’t get to work on for a while.
Call of duty 1&2 had an interesting cheat prevention method. Between levels the game unloads and reloads the engine dll. If you ever employ this method, make sure to include at least an md5 hash check. Otherwise I can just edit that dll and implant cheats into it.
