Sometimes being neutral to a situation feels like the better option. You don’t want to come off too eager or enthusiastic, even if you are.
And so you respond with things like ‘Yeah, maybe’, instead of just saying yes. That’s fine for some circumstances but it can also hinder you because being neutral can also be perceived as a lack of interest.
It’s important to remember that there’s a big difference between being eager or enthusiastic and simply showing that you’re interested.
