"You have to remember now, I was not being terribly successful at going solo"

John Sebastian's quote is a reflection on his experience as a solo artist. He is acknowledging that he was not having much success when he was pursuing a profession as a solo artist. This might be interpreted as an indication of humility, as he is admitting that he was not as successful as he had actually hoped. It could also be translated as an indication of durability, as he is still continuing to pursue his career regardless of the lack of success. It could likewise be interpreted as an indication of determination, as he is still making every effort to make it as a solo artist. Ultimately, the quote is a tip that success is not constantly ensured, and that it takes effort and commitment to accomplish one's objectives.
