I think work begets work.
Fruits are always of the same nature with the seeds and roots from which they come, and trees are known by the fruits they bear: as a man begets a man, and a beast a beast, that society of men which constitutes a government upon the foundation of justice.
I would say take any work you can get. Don't pass on something if it's a commercial. Take it. Work really does lead to other work. Especially if you're just starting out, work begets work.
Success begets success in terms of customer deployments and having truly happy customers.
So I feel like success is opportunity plus preparation, so work begets work, and as long as you're prepared it's going to continue to come your way.
My resonance to Magneto and Xavier was borne more out of the Holocaust. It was coming face to face with evil, and how do you respond to it? In Magneto's case it was violence begets violence. In Xavier's it was the constant attempt to find a better way.
