Love

Being in a healthy relationship takes work, but it's also surprisingly easy. It's difficult to take certain leaps, but you feel the benefits pretty much immediately afterwards. The main challenge is communication: sharing your emotions can feel too vulnerable for comfort. The decision you have to make is whether to feel vulnerable now and better later, or feel distress and resentment on an ongoing basis because you didn't share how you were feeling.

This is all massively overgeneralised, of course.
