"You finish a movie and you think, there, you've done it, really well, or best you can. But if you watch it, you see it was just bollocks"

This quote by Richard Grant speaks with the concept that no matter how tough you work on something, it might not be as excellent as you think it is. He is suggesting that even if you think you have done something truly well, it may not be as good as you think it is when you take a look at it objectively. He is also recommending that in some cases the work you put in may be for nothing, as it may be "bollocks" in the end. This quote speaks to the idea that no matter how difficult you work, you might not constantly get the results you desire. It is a reminder to remain modest and to not get too connected to the result of your work. It is also a pointer to remain open up to criticism and to be ready to make modifications if essential.
