Fail: But I didn't think that I had anything to offer, even though I had a different perspective on things.
Fail: But I still went to conferences listening to people spout things that I thought were nonsense.
Eventually I submitted for conferences.
Fail: But I missed a few conferences because I planned to submit but never actually got around to doing it.
Win: I submitted to some conferences and didn't get accepted. With each failed submission I generated more energy for getting my point across next time. And so I wrote more blogs, or submitted to another conference.
Win: And when I did get submitted, clearly that was a mark of excellence from the perspective of the conference organiser.

You should submit to conferences so that you recognise that you have something to say. You should submit to conferences so that you put yourself in a position where you have the opportunity to say it.
The deadline for Eurostar 2013 submissions ends on 13th February 2013. You should submit now.
