Anything the members that have been around for a while say doesn't hold any attacks. If they took the time to comment it's because they see a fixable flaw in your thinking processes.
The reason projection is a flaw is because it is is taking your thoughts and applying them to a self created framework of thinking. This frame work is based on what you want to believe and it's even worse if parts of it are true. The height of power is pure observation of reality, results are filtered through the preexisting framework. They are weighed and measured against what you know and then they are set aside and the situation is observed without the framework to see if the same conclusions can be drawn. If they can proceed, if not then the old framework is modified to take into account new variations that are now known to be possible.
The main point is that projection limits the potential of strategic ability.
With regards to the age thing, I don't know how old you are but from the context I'd say your younger. So I shall comment like you are. Yeah it can be an unpleasant situation. Once your game develops you begin to see that you could be getting laid a ton by giving focused attention. Everything comes at a price though, and your time is irreplaceable.
I'm 23 now, and had a successful career before going back to school. Honestly none of it made a difference except game and even then it takes time. They have a million guys trying to sleep with them, and they're interested in the older guys. Don't waste your time and potential on women who couldn't give a fuck about you and will discard you like a dried up dish towel the moment they find a better option. If you feel the need to get laid look for women that are older, not like late 20s though those ones are serious about finding a serious mate before their shelf life expires.
In the end Maraquee Value governs all, the time will pass and you will find yourself old enough in society's eyes. Idk about you but I want to be in the best position possible so I can dish out 2+ decades of glorious merciless payback
