tap in/tune in/turn on

[GUEST2008]

Hi

There's the sentence: If you want to be of help to others, be as tapped in, tuned in, and turned on as you can possibly be.

--- I don't understand what these three may mean? How to say it in different words?

[mara_ce]

I think that tuned in can be used in this sentence, which means to realize or understand what is happening or what other people are thinking.

[GUEST2008]

I'm not sure but to me these three mean that you should be watchful and concentrated.

what do you think?

[mara_ce]

I think that in this type of sentences only one option is correct.
