I took an 18-month break and I felt directionless too. I started with my bucket list: travels, writing classes, sports, organizing parties / trips with friends. But at some point, it felt a bit "vain"and my friends didn't have the same schedule. After this I decided to work part time on a contractor basis, and this definitely improved my level of happiness: having enough constraints to appreciate my free time more, having more people around me, being stimulated!
