I must say we have all made mistakes, but dang! I made some real hum-dingers when i first started online.
But the biggest mistake I made when starting is not creating an email list. When I did this, my whole business changed, I was making more money consistantly and a whole world of opportunity opened up soon after.
I use to come in here and hear people talking about having an email list, but I just kept putting it off. What a moron I was LOL.
What is your major screw up as a newbie???
