"I'm like the universe; either expanding or contracting at any given moment. The most that I had put on was about 35, 36 pounds, and I've taken all of that off"

In this quote, Sean Astin compares himself to deep space, stating that he is continuously changing and progressing. He explains that just like deep space, he can either be broadening or contracting at any given moment. This could describe his physical look, as he points out gaining and reducing weight. Nevertheless, it could also be analyzed as his personal growth and development. Astin then exposes that he had actually acquired a substantial amount of weight, around 35 to 36 pounds, but has effectively lost it all. This might symbolize his decision and capability to get rid of difficulties and barriers in his life. In general, the quote highlights the idea of constant modification and the power of self-improvement.
