B.O.B. Moment of Clarity

I've had many moments of clarity in this unit.  I find myself struggling and staring at a problem, and then when I go ask for help, and I'm like why did I not see this before.  Specifically for verifying problems or simplifying problems , I usually immediately understand and see what to do, or I just can't see it and struggle. Overall I feel like I understand the basic concepts of this unit, but when trying to solve its either a hit or miss.
