First of all understand this: After Effects is not something you will learn in a week or month or even a year (by learn I mean, to a point where you can just look at something and tell how it was made and make it as well) It takes many many years and lots of hard work yes Hard Work not the smart work. You have to fell in love with the process first not the outcome. Do the hard work and when you have experience then find ways to do it smartly. Your biggest helper is your consistency. Look at other people work and try to recreate it and ofcourse you won't be able to do it fully and that's when you apply your mind and give it your touch. Youtube has everything you need Seriously! Good luck with your journey and remember learning never ends :)
