I started leading teams relatively early in my career. Mentoring and leading younger developers is something I tremendously enjoy. But there is one thing I really miss about being a "regular" developer.
And that is - being able to put my headphones, play some rock 'n roll, and code for a couple of hours without any distractions.
Something that is almost impossible today. I'm not complaining, but the truth is that I really miss it. Luckily, I can fulfill my geek needs working on pet projects.
Cheers!
