I think the fact that you chose Technical Manager, and the reasons therein, says a lot about who you are. When your motivation is for other people that's a very good motive, in my opinion. Good technical managers are a rare treat and highly indispensable (both to their employer and employees), mostly because people who are talented on the technical side tend to shun management.

I say, "Congratulations!" and, "Thank you!" For all of us out there who wish that more dedicated talented people went into management. I'm sure you'll do well.
