Success as an author involves handling rejection and realizing that one rejection doesn't determine the future. Tying today's actions to tomorrow's destiny leads to paralysis. One must understand that all they can do is write, submit their work, and take necessary steps without being fixated on success. The concept of 'Karma Phala' from the Bhagavad Gita emphasizes focusing on actions alone, not the outcomes, as individuals are only entitled to their actions, not the results.
