Recommendation of "So-so"

Buddha told us an importance of "so-so". There are many examples of the importance of "so-so" on the book. e.g. "Don't look back the past. Don't wish the future. The past has been threw away. The future doesn't still come. Observe the current situation on your eyes. Just do it without your turbulence. Just do what to do today. Nobody knows whether you die or not tomorrow."
