Stained glass (彩色玻璃) artists create different designs by making cuts on the glass to “score” it and then breaking off the pattern that they want to use in the finished product. The most difficult cut in stained glass is called an inside cut. Basically, it’s a curved (弯曲的) line where you throw away the part inside of the curve. The problem with inside cuts is that the edges of the curve tend to break off when the pieces of scored glass are broken apart.

As the artist talked about inside cuts, he said, “The glass will break into pieces if you try to cut too much off at once. The best way to do an inside cut is to slice off smaller curves piece-by-piece. In fact, it’s not just the best way to do it, but it’s the only way to do it.”

How many times do you try to make a big change and cut the entire piece at once? We convince ourselves that we can do this all the time. We’ll commit to transforming our diet overnight or we get inspired to launch a business in a weekend or we finally get motivated to work out and push ourselves to the edge of burning out.

Why not approach your goals and dreams like a stained glass artist? Starting by slicing a shallow curve and breaking a small piece off, you cut a slightly deeper curve and break that off until you have your full inside cut. By slowly cutting deeper and deeper curves, you prevent the glass from breaking as it changes shape.

Of course, change isn’t easy — no matter how you do it. Slow gains are boring, but if we keep making small improvements, then pretty soon we will end up with a beautiful masterpiece on our hands instead of a bunch of broken pieces.
