Being a team leader isn't great if you are vulnerable to stress. I've never led a team but from how I see it their job is generally higher stress. You need to be technically hands on which isn't easy, and on top of that deal with any unexpected issues that arise, and yeah ... manage the people on your team. I honestly don't really know why everyone wants the job. Yeah it looks nice on a resume I guess..anyway I digress. Its the executive levels that perhaps get the good life but than you really leave development.
