What personal doubts and internal conflicts did the author face before beginning to write the Sai Satcharitra, as revealed in Chapter 2?

Chapter 2 provides a candid look into the author's personal struggles before undertaking this monumental work. After the idea to write the book arose, he was plagued with self-doubt, which he confided to Madhavrao (Shama). He worried that his age—having crossed sixty years—meant his intellect was no longer sharp and felt 'empty.' He feared that due to physical weakness, the effort might fail and amount to nothing more than 'empty talk.' Despite these significant reservations, he decided to proceed, reasoning that even if it was just talk, it should be for the love of Sai to achieve a spiritual goal, which was far better than engaging in useless worldly chatter.
