I am trying to learn how to do it myself but have too many things to make and not enough time.
Life is about choosing what you do and what not. I have the same "problem"
You should not "try to learn", you must just go through the samples of the tutorial section and redo them, read them out aloud to get their meaning. Within 2 days you can do many things and you understand the limits and possibilites far better. Your first question is almost explained there.
What is 2 days in a human life? => one month ~ 0.1% assuming you will be 80 some day
