Who are you playing tennis with?
There's a lot of volleying in tennis. They hit the ball, you hit it back.
A lot like most of the engagements you have with other people. The thing is, though, you get to decide who to volley with.
Perhaps you spend time with people who spend a lot of time talking to you about "who" vs. "whom" or ending a sentence with "with".
Or are filled with skepticism or negative feedback.
Or who deny the very facts that you've based your work and your future on…
It's unlikely that you'll change them. It's unlikely that they're making you better. It's quite probable you're spending a lot of time hitting things back that don't do you any good.
Consider playing with someone else.
Your agenda is yours. Don't throw it away without thinking about it.
