I don’t have an answer for you, but I’ve dealt with this same thing my entire life. It’s not a conscious decision, I just find that I never fully complete a task I set out to do. The number of games I’ve dropped 80-90% of the way through is staggeringly high. My home projects always get about 75% done and then are left alone, doomed to be unfinished. The only solution I’ve found is to set smaller goals. Tasks that require multiple sessions of activity before completion are very difficult for me and I quickly lose motivation. I also struggle with completing tasks if I have any sort of interruption, such as getting a phone call or stopping to make dinner. This is why I gravitate toward esports for gaming. I can complete a session within an hour and nothing is left open-ended. The problem there is that I actually prefer playing longer, story-driven games, I just can’t keep myself focused on them over multiple sessions
