Pruning a Pussy Willow Tree

Question

I have a 5 yr old pussy willow that has never been pruned and has reached about 10 feet tall. The newer branches and catkins are starting to only appear at the top of the bush just out of reach. I would like to trim it down so that it starts to fill in newer growth at the lower part of the bush. I have read to trim it down to 6 or 12 inches from the ground, or is this too low for the height of my tree? I want the bush to come back and I am afraid this drastic of a pruning will kill it. The tree has about 4 thick main branches at the base. Any advice you can offer is greatly appreciated. Thank you.
