Bad answer:

I was so tired of working and I needed a break or I just can not find a job.

Employment gaps are always tough to explain. You do not want to come across as lazy or unhireable. Find a way to make your extended unemployment seem like a choice you made, based on the right reasons.

Good answer:

My work is important to me, so I will not be satisfied with any old job. Instead of rushing to accept the first thing that comes my way, I am taking my time and being selective to make sure my next role is the right one.
