Doing something new is always challenging. The possibility of screwing up, looking foolish, creating problems for others. It is invariably stretching.
Taking a truck with a laden weight of 32 tonnes through tight winding London streets, with barely a foot clearance on either side, into busy and unpredictable building sites, and with potentially dangerous loading and unloading environments at either end, has pushed my limits.
A couple of mornings I woke with a knot in my stomach, my mind racing, and teetering on the brink of giving up. I don't need to be doing this!
But it's a challenge, it's good to be out of my comfort zone, and perhaps most importantly I have had great people, kindly and patiently, helping me. I didn't want to let them down.
Hanging in there and pushing through fears is worth doing as the pleasure of mastering a new skill feels great. It's what helps us to grow and find out about ourselves. I'm glad I'm doing it.
