I think there are some similarities with me but you came to opposite conclusion on blaming yourself for not fitting the world, unlike my conclusion, that world is not fit for me.

Just like you I am in pretty good physical condition and have no problems talking with women and also I have excellent skills in various areas of technology. I finished university with excellent results and little effort. But finding girlfriend was problematic because I simply do not meet that many free women. And now it appears that I am trapped between making money and living miserable life in routine like other people or doing what I want and facing uncertainty in future.
If I want to make lots of money I will not have any time for fun so life will be somewhat pointless. If I continue to live like now life is good, but it is not clear how long it will last like that and income is unpredictable and you still need some money to have fun.


Other people may tell you not to give up but I will say that even if you will manage to accomplish your goals they wont give you any happiness. And most likely you will really never find open minded woman (because that will requite to take unjustified risk and effort which will offset all benefits of being in relationship) but maybe you will be lucky.
Do you even know why do you need girlfriend? Just because you are told that this is what you must have?

You will not manage to build discipline or work ethic, simply because those things are meaningless to you. This is not weakness, but simply lack or purpose. The stuff which you want to accomplish is not what your really want. If it was, you woud be accomplishing it.
Taking a year off will not do anything good because you probably will never return back and you will have even less reason for discipline.

My suggestion woud be to give up on everything and focus on what you like, however at same time you should be responsible and work properly on accomplishing what you like. even if what you like if masturbating you must think on how to make that masturbation possible or if you will end being homeless or in jail it will be pretty hard to watch porn. But there is no point to seek any great accomplishments.
There is no problem being mediocre, because if you want to get higher you need to make more effort. really really matters is how much buck per bang you have to spend and how much you need to suffer doing what you dont like for getting what you want.
In that aspect I consider myself lucky, because I got more in my life than I deserved.

Your college, probably was a mistake by itself, because it will not give you any benefits and you may end up with debt which will ruin your life forever. (but probably your parent are paying for everything) Economy is not doing well and it will get worse so those your insecurities are pretty real. My university was also just a waste of time but at least i was getting paid and not paying myself for studies. So that was like some kind of job where you learn to get money LOL
