"Sometimes you'd come up against a brick wall... or sometimes you go into a fill and you'd know halfway through it was going to be disastrous"

John Bonham's quote speaks to the unpredictable nature of the creative process. It is frequently tough to understand what will work and what will not till you in fact attempt it. In some cases, you might have a concept that you believe will be excellent, however it ends up being a total failure. Other times, you might have a concept that you believe will not work, but it turns out to be a success. This quote is a reminder that creativity is a journey of experimentation, and that in some cases you will meet a brick wall, or have a fill that is a total disaster. It is very important to keep attempting and to not be discouraged by failure, as it is all part of the imaginative process.
