At first I really did not like it. Dealing with people is difficult and tricky, and there is a much greater responsibility.
I'm still of mixed opinion whether I'd want to do this for a long time. There are definitely perks. As an IC, I would get frustrated when I saw some organizational dysfunction. Now, I feel I have a voice and can do something about it. The trade off is spending more of my time talking with people rather than computers.
The other benefit I've found is my personal growth. I'm naturally quite introverted, and this has really pushed my boundaries. I've become much more comfortable leading discussions, trying to sell my ideas to upper management, and so forth. I've also had to deal with difficult people. Despite being incredibly tough at times, I've learned a lot.
I also care a lot about people on my team, and want to see them do well. I feel great when I'm able to make their lives better.
Still... I think I will probably go back to being an IC in a couple years. That is truly what makes me happy, and I don't think that is going to change.
