Language is cultural. I know I shouldn't have to say that, but it bears repeating, because we need to have this in mind when reading this article (and, at the same time, a similar one from a couple of years ago recommended today by Pocket). Look at the words from the first article (like, just, you know, feel) and the verbs from the second (think, need, want, guess, hope, suppose). When I looked at this list of words, the first thing I thought of was, "that's how Barack Obama speaks." Do you think these make you look weak? Or do you think - like I do - that their use signals a culture of empathy and thoughtfulness? It's up to you, as always, but just be aware of the choice you're making, and be aware of advice that programs default values like 'not being weak' into your thinking.
