Emotional stability :You have the image in mind; now you have to materialize it. And to do this you need hard work. You also need to have a calm approach to yourself and to others. You acknowledge that there are negative emotions, such as anger and anxiety, but you have to work with them rather than letting them overcome you. Indulgence is easy. There is a certain amount of gratification, but being able to control your extremes is a trait you certainly will find great use for in both your personal and professional lives.
Positive mindset: It is not easy to see the brighter side of everything, especially when nothing seems to go right. But you have to find a way- just one silver lining- in situations and in people. Include yourself in that list.
Self-Awareness: It takes a sagacious person to know his most authentic self. Your capability, who you are to others, who you can become- are all important aspects of your personality. You are not perfect, but as long as you enjoy learning from new experiences, you will become better. However, the learning is not a passive act; it is an active effort to progress, and it works wonder for even the most mediocre person. Politicians learn to speak publicly, arts students learn to code. You analyze your strengths and weakness and work accordingly.
Flexibility in behavior: Adaptation is critical to biological evolution because it provides improved function. Color change to camouflage from predators, a protein that works better with the change of environmental temperature, an anatomical modification that helps forage for resources- these are not very different from the psychological perspective of adaptation. You have a different persona for different people. You will not engage your 5-year old nephew in the same way you'd deliberate with a professional relation. There is no con in it; just an improved function to converse more efficaciously.
