I would definitely recommend giving a lot of thought to some of the intangibles of your application as you gear up for your cycle. You have awesome stats, research, and experiences, so to set yourself apart, start thinking about how you can weave these experiences together into a cohesive story (e.g. how did one experience inspire you to pursue another, what are some uniting themes of the activities and research you have engaged in, etc). Crafting an application that is more than the sum of its parts is a great way to help you stand out from other applicants with similarly excellent backgrounds.
