The habit that makes me a worse founder every time I do it

I check my competitor's product every morning. Not productively, not with a plan. Just a quick scroll to see what they are doing.

It is the worst ten minutes of my day and I keep doing it.

The thing is, I never feel better afterward. I feel either behind or briefly superior, and both are useless. If they shipped something good, I feel like I am losing. If they shipped nothing, I feel smug for a minute and then weird about being smug.

Neither of those emotions makes my product better. But the habit is sticky because it feels like diligence. It feels like I am staying informed.

The truth is I am looking for reassurance and finding anxiety. And the actual work is sitting on my screen the whole time, waiting for me to stop scrolling.

What is the habit you keep doing that you know makes you worse? And what would happen if you just stopped?
