The people you have helped in the past are countless. Sometimes certain people (artists) take the time to remind a few promoters out there, and thank them for being partly responsible where they are now in their career. Sadly, some artist wouldn't want to do anything with you.
Personally, the people that have helped me in the past, well, I can count them easily since they're very few. In today's world, don't ignore the very people that have been by your side supporting you whether it is convenient for them or not. Their love for you is unconditional, and they have been with you since the beginning, mistakes, bad decisions or not. Surprisingly, there are certain good people out there that started helping you out and you don't even remember what you have done for them. Yet they remind you that you have done something for the community as a whole.
It's very easy to forget, or at worse, ignore a person who have helped you in the past, because he is at the bottom, it's very convenient to disregard him, not support him and side with others that has never done anything for you in the first place. I've seen things. I heard stuff. I've seen certain people being put down, being blasted, and being slammed in social media.
***Giving an upcoming artist (dj, performers, teacher) a teaching gig; Recommending them to other promoters; putting them on guestlists; giving them huge discounts when they request one; giving them honest constructive advice after judging them in a dance competition; supporting them and promoting them when they were rookies, or getting played out; Defending them and their reputation when need be...In this industry, these deeds are not little, they make a lot of difference, and most of them are priceless. Imagine if you are actually getting charge for each good deed a promoter has done for you, or the community as a whole.***
What I have noticed in the last 2 years, at least for me, is that promoters, that were once competitors have become friendly and gained respect for one another, and at times, actually look out for each other. Of course, this is not the norm, I hear bad breakups in the "promotion" with business partners suing each other. I went through that in my 2 year of promoting, and it was very ugly.
To those of you that just "don't get it", try going into the dance congress promotion business, don't get partners, just you and see what happens....or how about this, what if there are no promoters running an event for a year? What if promoters actually unite and protest for not running any festival, clubs, bootcamps for a while?
