Fig.: having or pursuing multiple opportunities simultaneously

I'm looking for a different, more interesting job and I have a number of irons in the fire

Mi sto guardando attorno per trovare un lavoro più interessante e ho diversa carne al fuoco

Blacksmiths traditionally worked iron into shape by hammering. The iron being worked would be heated in the fire until it was red-hot and malleable. The blacksmith removes the iron from the fire and shapes it with repeated blows from a hammer. They need to work quickly before the iron cools. Once the iron is cool, it becomes brittle and cannot be hammered. Once removed from the fire, the iron cools quickly. It takes longer to heat the iron to red-hot than it takes for it to cool. Blacksmiths work more efficiently by having multiple pieces of iron in the fire heating simultaneously. In that way, the Smith can always have a piece of iron red-hot and ready for hammering. The cooled piece would be returned to the fire if it needed more hammering
