hyphenate only when the word is too long for one whole sentence

There are already many questions about hyphenating words, but I couldn't find a question about hyphenate only when one word is too long for one whole sentence.

example:

I like this to be intact (not trying to put the word "opportunities" in the upper line with hyphenates)

But I want to have a word that doesn't fit the whole line/div/page is hyphenated. Otherwise I can't see the text in full. (now it cuts off the last 3 characters)

All the solutions I have seen before on other questions does hyphenate on both examples instead of only in the last example.

I don't think I am the only one who counters this issue?
