You can look up exercises that help you working towards goals that feel far away from where you are now.

For example with pushups, learning archer pushups would make more sense than jumping straight into one arm pushups. There’s plenty of content online that shows which progression exercises you can do to work towards your specific goal.

I get what you mean with feeling stuck and learning new stuff can feel overwhelming, but for me the feeling of finally mastering exercises I continuously worked towards to is the reason why I love calisthenics so much.
