I have talked to some Spanish speakers who tell me that the overuse of direct pronouns are indicative of native English speakers learning Spanish. I am told that this constant use of direct pronouns is redundant. Most Spanish speakers rely on the conjugated verb to understand who is doing what.

However, I am one of those people, Out of habit, as a native English speaker, using he, she, you, me is just natural....

Good luck on your language journey!

It surely is a tricky part of Spanish grammar. It turns out that besides its usual role as a reflexive or reciprocal pronoun, "se" is often used in constructions where no reflexive or reciprocative meaning is intended at all. The meaning it conveys is in those cases dependant on the specific verb we're dealing with, and is hard to accurately explain. All that said, it most commonly imparts some idea of incipience or spontaneity on the part of the speaker; the latter means it's commonplace in casual conversation, and less so in the written language. Whatever the case, the nuances of meaning differ only slightly, and the instances where it occurs are better learned as idiomatic expressions.

Ella comía hamburguesas todos los días     (For some reason I don't know, idiomatic "se" can't be used when the object is a plural noun with no determiners preceding it)    

Ella (se) comía tres hamburguesas cada semana

(Me) iba a casa de mi abuela todos los días después de clases

(Nos) leímos el libro entero en solo tres horas

Leímos libros toda la noche

 Of course, not all verbs admit of this idiomatic use of "se" .  I hope you understand the grammatical parlance. In case you don't, I'm sorry, but I don't think I can explain this in lay terms
