Rajesh Khera, popular for his role as gay designer Maddy in TV show "Jassi Jaisi Koi Nahi", says actors live on the edge because of uncertainties in their career and the feeling is scary.

"As an actor we live on the edge. We are not sure of our next move. If one serial gets over, we don't know when we will get our next project. So you are only earning for that period of time," Rajesh told IANS.
