My advice: each repository should have a reason to be shared.
It is a project people are interested in (it has stars and/or forks).
It is a collaborative project.
You think it is useful, your personal alternative for other software or it shows your knowledge of certain topic.
I use to browse GitHub and honestly, repos like these make me leave a profile in seconds:
Android Test
Hello World Java
To Do List Web App
Any undocumented and simultaneously unactive repository (that's just noise).
Programming exercises solutions (unless it is a collaborative compilation, no one wants to see them).
etc
Not shaming people who have them (I've not seen your profile so sorry if you have some of these, not my intention) but these are not interesting nor tell anything about you, except that you are learning (hey, it's better than nothing).
But, if you have better, more interesting projects, get rid of old uninteresting ones. Quality before quantity.
