- Be organized and responsible
- Write everything down from meetings with clients or developers (insurance)
- If something bad happens, it's on you. If something good happens, it's on the team.
- Review everything, carefully (especially code)
- Don't blame people for their mistakes, compliment them for their assertions (How to make friends and influence people - Dale Carnegie)
- Use a calendar app to manage your appointments and never lose track of time (You should be able to manage your team and also get your tasks done)
More importantly, don't be afraid of making mistakes and don't freak out due to the amount of tasks. Exercise your body (running is a good option).
Be proud of yourself, you made to lead developer!
Cheers.
