There's always something to do in KSP. Jump in and have some fun. KSP is one of the most awesome open-world games around in that there's never an end, even with career mode. Fling a Kerbal at Kerbol, just to see what happens. Try and give Kerbin an asteroid belt (for fun and profit?). Set and break some land and air speed records. Find a mod or two and you'll be amazed how much the game changes. Besides...."waiting for 1.0" is a bit of an open-ended timeline
