I just don’t have the motivation to get over my nervousness and do it

I wish I had a magic wand or a One Weird Trick that could get ya over the hump. In my case the new gig was all but gift wrapped and placed into my hands for me. That's what it took, and seeing how much it had to be handed to me just made me feel worse too. All totally unhelpful thoughts but that's where my brain goes with it.
