だが同じ本を読むことでも、同じ本を話すでもいいからやってみたほうがいい。

Question

だが同じ本を読むことでも、同じ本を話すでもいいからやってみたほうがいい。

Does anyone know what the いいから means here? My guess: "But, the same book to be read, the same book to be talked about is good to try?" What would the difference be if I took out いいから and just said: だが同じ本を読むことでも、同じ本を話すでもやってみたほうがいい。

Would the meaning change?

Answer 1

This sentence has the ～で(も)いい construction to express something is fine/acceptable (if not ideal).

• What is the difference between それでいい and それがいい here?
• Maggie Sensei: Noun + で(も）いい　VS +がいい ( = Noun + de (mo) ii vs + ga ii)

This sentence has two でも, meaning whichever is fine.

• XでもYでもいい
  = XでもいいしYでもいい
  X is fine and Y is fine, too
  X or Y, whichever is fine
• 同じ本を読むことでも、同じ本を話す(こと)でもいい
  reading the same book is fine, and talking about the same book is fine, too
• 同じ本を読むことでも、同じ本を話す(こと)でもいいからやってみたほうがいい。
  Reading the same book or talking about the same book, you should do whichever you like (together with your girlfriend).
