I'll say
Enough working on the DSA repo for WOC.
Try other repos please.

This will help you expose yourself to many other repos in the contest. You can come back here after trying out other repos!!

If you still want to contribute here (not good for you considering the motto of WOC) - will assign.

Sure will look out for issues in other repos.
