Learning new things from your colleagues can improve your chances to upgrade your career.
Looking up to your colleague
Sound technical skills are the core features of a good programmer but soft skills are equally essential as well. The developers should be proactive, and work out of their comfort zone.
Work on your soft skills
To become a good software engineer, you need to follow professionalism. Choosing the right set of values is important for software developers.
Set your own values
It is okay to focus on a single programming language, you should always be on outlook to learn more languages, algorithms, and concepts.
