This is kind of an odd question... but here goes.<p>I love to work. When I'm really into a project, I'm the type of person who can go at it from the time I wake up until the sunrises. It isn't uncommon for me to forget to eat (have to force myself away from the computer if I am really into a task!). Last summer, I did this for a few months straight, 6 days a week (weekends, I'd take it a little easier).<p>But the weird thing is, I enjoy it. I am excited to wake up in the morning to get started on where I left off. It feels great to polish off a few features before going to bed on a high note.<p>My question is, how do I know if I'm overworking myself? Am I stressed? It doesn't feel like it, but... yeah, what are the signs?
