Avoid trying to "hide" gaps with functional resumes or removing dates. These are instant red flags. Have an explanation ready to explain in the interviews, but do not make it a big deal.

It is fine to take time to work on themselves and figure out what they are interested in. A good way to get something on their resume is by doing projects or volunteer work that is relevant to what they are interested in. It's a low commitment way and lesser barrier to enter. You can write it just like work experience on your resume.
