- It really is a brand new skillset. You will probably hate it for the first year. Stick with it.
- Remember how you had this big engineering problem so you just worked more hours to fix it? You can't do that anymore. The scope is just too large, so you can't outwork your problems anymore. You have to have a team that can handle it.
- Be good to your team, but remember: if you get fired they aren't going to quit with you. This might be the most controversial point, but if a team member isn't performing then you will have to make the call to shield them. Don't do it enough and you will de-motivate your team. Do it too much and you'll piss off an exec who will remove you.
Overall, a great experience but it isn't for everyone.
