Guess the job market is now an Employers' Market. The golden
days for employees, where we can pick and choose our jobs, and the
perks are attractive, doesn't seem to exist liao! 
So yeah, better to secure a job first before making that leap of
tendering your resignation. Unless you have enough resources to see
you through the next few months or unless you don't mind taking on
some temporary assignments in the meantime.
Guess you need a break, huh? 
Well, depends on your field too, I guess. If you're in a field
that's in high demand, you won't have any problems. 
BTW, what field are you in, if you don't mind disclosing, that
is.
