It took me a while, but I got my first 5.13b on lead a couple weeks ago. One thing I have to say about that route is that it opened my eyes. Since I started climbing, I've had this general idea of things that are out of my reach, my body isn't ready or I don't have good enough technique, there's always some kind of reason in my head. Recently, I have been trying things out with my body to test my strength: front levers, psudo-planche, muscle-ups, the like. I have realized one thing that all climbers should try to understand. My body (and yours) is ready for the next level, your technique is good for the next grade, and you don't need to be able to hold that lock off on the bar for fifteen seconds to be able to do hard climbs. When I topped that 13b, I didn't feel extremely tired, my pump was bad, but I've had worse, sure the crux was delicate, but I could do it. All of this, I was capable of because I started to believe in my capabilities and realized that the distance I was pushing myself before was short, I could go further and further. Get out there and push, find your limits and break through them.
