I remember back when I started (quite a long while ago now) I had no clue what anything meant. All these buzzwords, abbreviated terms, concepts about literally anything marketing related at all I had no clue what so ever. It's just part of the journey, nobody is born knowing this stuff. Just like when we were children you've got to learn to the alphabet before you can write and you have to learn to write before you can express your ideas with written words... just take it a step at a time and don't let that nagging feeling of "gotta go faster!" get to you too much. Believe me when I say, we all feel it sometimes and you've just got to let it go and focus on the training and getting more experience.
