If you set a deadline to find a job and can support yourself for that time, why not?
I didn't do the setting a deadline bit, so ended up on a 9 month holiday when I first moved here
Moved to Taiwan in 2012, no job lined up, very little money, and just had two friends here who I met briefly in Thailand in 2006. Got very lucky with a seemingly endless stream of local expats willing to let me stay with them for a month or two for free. Took my (then) girlfriend back to the UK for a visit, and lined up a job before I came back.
I quit that job after two days and was back to square one, but worked out in the end. I know I got very lucky, but have no regrets about moving here
