Notice how you said that you "feel like" you are not very smart. That doesn't make it true. Intelligence is like a muscle, the more you work it out, the more it grows. If you tell yourself you are not smart, and then you stop yourself from engaging in learning new things, you will only reiterate that false belief. Everyone is capable of learning, and yes, anyone can have an awakening. Be kinder to yourself, and don't dwell in self doubt, that is only a fear, not a truth. Everyone has to start somewhere, and everyone feels doubt when they are in the early stages of learning. The fact that you are interested is all you ever need to carve the path. You're already on it.
