If you’re leading a team, there is only what the team has accomplished.
There is no “I” that has been done. Everyone contributed in some fashion – whether freeing you up to do that work, doing the leg work for that work, taking on extra bugs so you could focus, or not disturbing you while you did all that work.
They might not have banged out all the code, but what they did do is help give you the opportunity, time, and space to accomplish that work.
The team helped.
