I may offer an opinion different from other responses you receive...

If you're not unhappy where you are--adequate salary, good living conditions--then take things slowly...

Land the next job before leaving your current one, and only if it represents a step up in responsibility and seems interesting, or otherwise improves your "life"...

Look at the headlines on the worldwide economic situation just now...yes, things are a bit uncertain...do your homework before making a jump...

And don't undervalue having a job when things are uncertain...just think about the alternative...
