Freedom of application. There was a lot of room to experiment in methods that could lead to success.
What I wish was different
Communication.
Advice
My advice would be to be comfortable making mistakes and working on efficient communication. If you're unsure of what is expected of you after a meeting, send an email summarizing the meeting and what you took from it. List what your interpretation of responsibilities are so everyone is on the same page. This will help you you limit any miscommunications.
