The first few times you are a reviewers are great and wonderful experience. It gets boring quick. One out of 10 papers is a good read. The rest are badly written or unnecessarily complicated. It takes a lot of times and efforts to review a paper. I used to be quite excited to review papers. But now, I decline almost all incoming invites. Just not worth the time.

The only good argument for reviewing is community service. You basically volunteer your time to make sure the community is strong. So, if you are still submitting papers for others to review, you should be doing the reviewing yourself.
