More room for options
There is usually a phase of inner reflection at the beginning of these kinds of breaks in which you make yourself aware why you require distance from your daily work life, what is important for you, what you would like to try, and where you want to put your focus on. Of course, this can also precede any regular vacation, it is then, however, less extensive in comparison to the wish for change that precedes a sabbatical.
In general, you can use a sabbatical for traveling, taking lessons, acquiring new skills, and following personal or professional goals that can even help you in your career. Also volunteer work, taking time for a hobby that you hold dear, or realizing a project like building a house can be ideas for a sabbatical. Beyond that, a sabbatical can also be used to spend time with your family, to care for a relative, or to consciously slow down your daily life in order to prevent a burnout.
