1) You might want to consider quitting your barista job.
2) You might want to spend more time studying and less time playing video games.
Q1): I know "you might want to..." means "I suggest/recommend...". Do we use "you might need to..." to mean the same thing too?
Q2): Can I use sentence (2), or rather "you might want to...", in a different context where the speaker is not sure whether "you" intend to do the thing mentioned, and therefore just guessing "maybe you want to do X or maybe not, I don't know"?
