East West Commercial Real Estate

I am 22 years old and looking to get in the commercial real estate industry, preferably the leasing aspect. What would be fundamentally required for a person as young as me to be even considered for a job in a large commercial real estate firm? Considering I have a real estate agents license, what else would be needed or would interest a company in hiring someone so young? In other words, how can I get my foot in such an industry, thus giving me a chance to work my way up?
