Do you remember the first day you started a new job? Everything was so confusing, you felt like you were never going to understand what this person was trying to tell you. I remember my first day in radio and David Crawford was explaining traffic to me, and clocks and logs and scheduling. My head was spinning. It took me several weeks to figure out what the heck he was talking about.
It feels the same way today while I'm learning how to take photos with my new Nikon D3200 in manual mode. There's ISO, Aperture, Shutter Speed, White Balance, fast, slow, high, low. It's VERY confusing to say the least.
