Hey Dirk!
Welcome to the world if RE Agenthood.
I too got my license. I came out of my test and thought "Umm..... so.... now what?" Now, nearly a year later, I'm only just hanging my license with a broker and planning to do something with it. I however will not be doing any traditional real estate work. Mine is 100% focused on investors. So it's a little different ball game.
That said, everyone I know in RE tells me that one can never do enough door knocking, local media, cold calling, advertising etc. In my experience, and this is only in what I've seen in hanging out with other people I went to RE school with and watching their careers progress, they spent the first 90+ days just getting their names out before they really ever got enough attention to do any actual contracts. That being the case, I'd say START NOW! I look at it this way, if you have someone who moves faster than you're ready for, you've got your mentor and more important, you've got your reason to "figure it out in a hurry!"
There's a saying you'll see around these forums a lot. "Progress, not perfection." As much as I hate it when people say that to me, it works. It's worked for me. At least in this arena. Not so much in my other professional life. I think this is why I was so resistant for so long. However, once I started just "doing something" I learned a lot from just doing it. (mostly wrong) LoL.
Lastly, like I tell the people who come to my Empowerment workshops/seminars (Firewalking and the like) "You don't have to be ready. Just be willing." I think this applies to all our endeavors. If you wait until you're "ready" to do this, that time may never come.
Good Luck Brother,
GB
