The other day I was complaining to a friend about something that didn't go as expected, and the person who had been listening quietly for a while said, “But that’s actually not such a big deal, right?”.
Indeed. If it weren't really okay, I would have been running around trying to fix it at that time.

In the video "Painting", you can see the process of creating of abstract works by the world-renowned German painter Gerhard Richter in detail.
Even if the work in progress already seems quite beautiful, he runs a wide squeegee (like a board with a handle attached) boldly over it. 
This can cause the colors to mix, hide the paint that was at the top, or suddenly be pulled to the surface by another squeegee operation.
This process is repeated hundreds of times, and the work is complete when, in his words, there are no more possibilities for additional moves.
Destruction is " not such a big deal", I was really convinced by looking at this.

Destruction is a tricky and interesting entity though, sometimes necessary to give a work strength, sometimes emotionally disliked, sometimes a symbol of courage, and other times perceived as the result of stupidity (e.g., having made a mistake somewhere in the process).
I found it interesting that Richter's technique seems to be quite purify the act of "choosing" in the creation, by simultaneously destroying and creating, while giving up complete control over the outcome.

Nevertheless, the way we look at things is influenced by the techniques we use.
So, the above impression of the squeegee process may be because I've been using collage technique.
After all, "choosing" is at the heart of collage process.

Anyway, I believe that "Destruction is okay – not a big deal." now. 
And think it is a stance worth keeping, both in creation of art and in life.
