Preheat oven to 350 degrees F.
In a large bowl, mix sugars until well combined. Melt butter in the microwave and add to sugar mixture. Stir until well combined. Add vanilla and eggs and stir until well mixed. In a separate bowl sift together flour, baking soda, and salt. Add dry ingredients to the wet and stir until just combined and NO MORE! The dough will be stiff. Add chocolate chips and nuts. Stir until just combined. Avoid any extra stirring to avoid tough cookies. Line cookie sheets with parchment or waxed paper. Drop dough onto sheets with a small ice cream scoop. Flatten the dough slightly with your hand and bake 10 to 12 minutes or until edges and tops of cookies are just turning brown. Cool on wire racks.
