It really depends what type of Animation you're doing. For example if you're creating a 3D animation, then it would be pretty difficult because there are a lot of steps you'd need to follow in order for it to be successful. However, animating can frustrating and tedious. It also takes time and practice if you really want to make a career out of it.
Most animators i know complain about how hard it can be to use specific software to convey their vision. Some of the software can be challenging to learn or requires more expensive equipment to execute well. The two animators I know right now where I work had to have computer upgrades to handle the sheer power of a tool like Adobe Character Animator and Adobe AfterEffects.
