Stop or go?

I don't know weather i should wait or if i should continue on. This is just so hard. and its funny how its like karma... the same exact thing is coming around my way, except I'm in a different position. I am so confused and its frustrating. I feel like life is so short and it goes by so quick so i should just run to an open chance... but then yet i wonder if something good is actually worth waiting for... or is that just another one of those thrown around phrases that really aren't true. whattodowhattodowhattodo.... gah.
