Corporate aviation is very network-centric. Ability to fly the airplane is one thing, personality is just as important. If you are a social door knob, you will not be asked to go along.
The previous recommendation to fly airline first is good as it provides good training, structure, stability and time building. If you walk in the corporate door with no experience, your success will probably be a result of knowing someone or being very lucky.
