Literally, if someone says I am grounded, everyday I am at home, I actually have my hands in the ground and dirt under my fingernails. I don't have a staff to do it all for me. I still plant a seed and I'm amazed it grows.
It's kind of a rule of thumb for me to self-doubt going into any kind of project. I always think that I shouldn't be doing it and I don't know how to do it and I'm going to fail and that I fooled them. I always try to find a way out.
