Haru, I will give you my sincere and honest advice: you do not need to go anywhere. Just stick with your computer and work hard. Or go to onsen and relax and then work. It is IMHO much more productive than wasting time.
I can not say the conferences are useless, because I actually never went to one of them since 2006 when I made my first affiliate account. But that also means that I did not miss the conferences, right?
The bitter truth of this industry is that the affiliate programs want you to come to the conferences and give them traffic for cheap. E.g. they will promise you there everything and then they will deliver nothing. They waste money on marketing themselves, instead of just paying people.
So again, my advice is to sit by computer, do your research, stick with programs that have history of being honest. And get the traffic. You do not need more.
If you talk to God, you are praying; If God talks to you, you have schizophrenia.
