There’s always a comment. No matter how great your effort is, how flawless your work, someone can do it better.
They’re whispering, “Your competitor is further along. Another company has edged you out this quarter. Her work is getting more publicity, more recognition.”
You’re spending time reading comments. “His project is scoring more funding. They’re getting all the sales.”
It doesn’t matter.
Keep on and stay the course. (It’s your course and your course alone. Not theirs.)
Do your best work, no matter what they say.
