Can I be a real estate agent?

I was told the income for a real estate agent is quite well paid. But sad to say, I do not have the negotiation skill to do the bargaining with customers; else I think I can try to venture in this field. My bargaining power is weak and I notice myself do not have skill to convince my customer to do any purchase from me. Looks like I still have to still to my administrative job for the rest of my life.
