How often have you heard yourself utter, "you cannot get there?' or "you cannot believe that!" Are you aware that this is self-defeating? You can evolve to change the way you seek what it is you want. You may not yet grasp what is or isn't working and why.
Knowledge isn't something you acquire. In fact, if you pursue knowledge or happiness or anything you asume you don't have, then you already sense you cannot have it. Its an unconscious way to reinforce you don't deserve something or, aren't meant to get it.
Another approach is to believe you have innate wisdom. You are happiness. You are joy. This kind of perspective emerges out of a different kind of self-awareness. When you pursue something, you assume its out of reach. Why not visualize differently?
Think back to when people have asked you what you do. You may have said, "I'm studying to become..." or, "I'm training to be a..." as if you were tentative or hesitant to define what you feel you are. No matter how you earn your living, this is only an external label.
When you develop muscles like body builders, then you develop the outward strength and resilience earned through the training and weight lifting. Similarly, as you evolve to experience complete self-awareness, you will be able to do, sense and experience those things that beings in a heightened state of awareness do. To move into this state means believing you're there is no longer necessary. Rather than believe in becoming, just be.
