One of the best ways to learn is to study what others have done; that is no surprise. If you wanted to be a soccer (football) star as a child, you probably watched Pelé on TV and imagined yourself scoring goals the same way.
Animation is the same. It's good to watch the animations that others have made. The following animations are a few recommendations that you can try to create:
Oswald the Lucky Rabbit, Trolley Troubles
Felix the Cat, Woos Whoopee
Popeye the Sailor, The Paneless Window Washer
Betty Boop, Minnie the Moocher
Lotte Reiniger, The Adventures of Prince Achmed, made in Germany
Jiri Trnka, Ruka (The Hand), considered the Walt Disney of Eastern Europe
Ivan Ivanov-Vano, Blek end Uait, made in Russia, which may be disturbing to some
Quirino Cristiani, El Mono Relojero, made in Argentina
Please remember that the times and values were different, and watch the animation and not their attitudes.
