Raise hell, or bugs, on CPAN Day!
If you've got one or more distributions on CPAN, then on CPAN Day you could go through them and see if there are any ideas you've had which aren't listed in the issue tracker (typically RT or github issues).
If you don't have any distributions on CPAN, then you could go through the modules that you regularly use and see if there are any issues you could raise.
I'll expand a bit on what I mean, and why it might be a good use of your time.
