When I see the work I do sometimes, and especially how, I still wonder why I'm still in good health.
Also tricks to get things done are sometimes on the edge. But work has to be done, this way or a other way around.
Working on heights was always a little big, sometimes scarry thing for me to do. But practice works. I'm not running up that stairs, but a certain confidence is what I found along the way.
What safety is all about is to think and to do. Not just thinking it's allright, but ponder first how it will be done.
