Of course you would fail, you just self proclaimed that you would so you would self fulfill that prophecy. And then you go on to explain how you have a lack of patience. What you really mean is I'm lazy af and I give up easily. In order to accomplish anything in life, you will first need self belief, and then you will need to be patient. Sounds hard, but I assure you that with a constant effort made on your part it can become much more rewarding than pretending to be an idea man when all you do is regurgitate commonly posted ideas. You are better than that.
You have passion but you shoot it down without even trying. Make a choice, and do something with your time here and do it well. So what if the first 5000 steps suck eventually you'll get better and pretty soon people will praise you. I am a nobody from nowhere, but I turned my passion into a multi million dollar a year business. But I always had self belief, because mom told me so. Even if it was a lie, it got me started and that momentum is very powerful once you harness it and decide to do better than yesterday. So get off your ass and make something of your life. Believe it or not you will blink an eye and be 30, and then 40, and then wonder why you didn't get where you wanted to be if you don't apply yourself.
If you don't make a choice its still a choice. You'll be flipping burgers and not getting any respect, not be happy etc. So its better to try to become something and fail, than to do nothing and succeed. Use your passion to make mods, or become a good artist, etc. You like attention and working on mods is a great way to get some and build your skills up.
