Truth be told,I just don't like this world. I, and I suspect most people, can endure a lot if the result is something they think is worth it.
I can't see a worthwhile reason to endure life as we currently live it. I know it'll get better, but I can't see it getting good enough to make the journey worthwhile. The world doesn't revolve around me, any progress will be made by my efforts alone. Yet I'm only human, and no matter how much effort I put in, I can clearly see where I'll end up, and it's still nowhere near where I wished I could be. I get my expectations are impossibly high for life, but knowing what's realistic and what's fantasy only adds to the disappointment. As someone already posted, I don't have anything in life to look forward to, to make the journey worth it. If I even make it to the end. Sometime people just fail despite their efforts, and every failure puts you further and further away from any end that was obtainable and worth while.
