Teams are made of people, not systems. I think this is self explanatory.

Letting your passion shine through, and letting your personality come out in your work is, for me, really important. When you enjoy your work, it is great to let that show as it helps others see that passion, and shows you are motivated and engaged by what you do. I also think it is really important to be open and honest at work at well. Let your manager and colleagues know how you are feeling, and don't be afraid to ask questions - especially in Trading, asking questions is so important in helping you learn and understand the role.

As Quality Assurance, we always work with that concept in mind: design, test, feedback. Don't stop any of these 3 things... ever. You can try everything; you can test and arrive to a result. If you manage to understand the potential to improve based on the result, you are in the right position to improve the quality. This will mean you have in mind the entire flow and things to improve. Don't stop yourself!
