I found the perfect balance to be very pro-active and resourceful at the beginning of a project, both to structure it in a way that suits me and make a good impression. Later, not so much. And I am not lazy, but being too active means other team members (or even the customers) get too little say.
Highly reactive employees and companies end up being left in the dark and given short notice on everything... leading to more stress
A balance between pro-active and re-active is ideal.
