I find trouble to distinguish when to employ -ing or infinitive in certain cases. Have a look at the examples I came across on a book: - Discover the secret to getting through to anyone. - 7 steps to living at your full potential.
Based on that, I wonder if it's correct to say: discover the secret to GET, and 7 steps to LIVE. Why to use -ing after the preposition "to" in such cases? I know some verbs have the ing- form such as: look forward, dedicate, commit; but I've never seen "to getting" or "to living" after a noun as "secret" ot "steps".
I'm grateful in advance!
