Does my phrase sound natural "This book has been an eye-opener to me..."?

[Zoli]

This book has been an eye-opener to me and caused me to develop an even deeper appreciation for computer programming.

 

[Zoli]

Can I also add "an even deeper appreciation for computer programming than I had before." ?

 

[Tdol]

Than I had before is unnecessary- the logic of the sentence makes it superfluous.

 

[Tdol]

PS The original sentence is fine, though I would say made me develop.

 

[Skrej]

I would say 'an eye-opener FOR me', rather than 'TO me'. 'To' strikes me as at least unnatural, if not incorrect.

"Eye openers" are usually real. "That was a real eye opener for me."

"Eye openers" as usually real. "That was a real eye opener for me."

I'm not sure what you meant to type but I don't think it was that!

[SoothingDave]

Yes. "Are usually real."
