This is my advice for someone looking to get into animation:
Persevere. Never stop, even if it’s really hard, because animation is really, really hard and takes lot of energy.
Enjoy it. If you don’t like drawing lots of frames, don’t force yourself into animation (I say this mostly for frame-by-frame style animation, there are many other styles of animation that you can try which don’t involve as much drawing).
Rest often. Don’t over-do it. Even if you’re not happy with what you’ve drawn, or you think it’s horrible, save the drawings and look at them regularly to progress and keep going.
Be inspired. Look at the work of animators you like, and try to understand how they work. What are their techniques, why you are so inspired by them?
Share your work! Don’t be scared to share your work, to ask for feedback and critique. This is what helps to build you as an artist.
