Do goals, and keeping persistent


Hi Brooke,
I’m a newbie here, but loving the concept of having “do goals”: keep taking massive action until you get the result you want.

Now, I’m trying to fill a group for a training. I know that if I just do enough 1 on 1 sales calls, I will get enough people to sign up for the training.
But I’m having trouble getting people to register for a sales call in order to get them to sign up for the training.
Meanwhile the deadline for the training is coming closer and closer (11th of october).

I KNOW I can fill this group. IF I can get enough people in a call. Even if I have to do a 100.
But deep down I’m afraid I won’t be able to get enough people to register for a call before the deadline, so I won’t get enough people to sign up for the training in time.

So how long do I keep going at it, before I postpone the whole thing to add more time to do whatever it takes? Or even better: how can I go to believing I CAN get enough people to sign up for a sales call in time?

Thanks
