What does the following sentence mean? "However, sometimes the messaging we receive to be giving of ourselves, to push ourselves to the limit, be productive, and forgo our needs can be taken to an extreme in our everyday lives." What does "to be giving" mean there?
The business-hip word messaging is pretty much a collective form of message, and it takes the same sort of marked infinitival complement:
We received a message to meet them at 2 o'clock ... that is, the content of the message was that we should meet them at 2 o'clock.
He sent me a message to bring him the report today ... that is, the content of his message was that I should bring him the report today.
The infinitivals in your sentence work the same way. Paraphrased:
However, the messages we receive—exhortations that
- we should be giving of ourselves ... that is, we should dedicate ourselves to the benefit of others
- we should push ourselves to the limit ... that is, we should make strenuous efforts to achieve more than we believe we are capable of
- we should be productive ... that is, we should strive to produce real, practical, valuable results and not be content with merely expending effort
- and we should forgo our needs ... that is, we should not attend to our own immediate needs.
—these messages can be taken to an extreme in our everyday lives .. . that is, we can take these messages too seriously and spend too much time and effort trying to follow them.
