I waste time on Reddit during the work day or when I know I should be doing other things. I don't necessarily consider it wasting time as I've found that diverting my attention to something unrelated to what I'm working on from time to time helps my mind to focus in the long run.

Reddit is easy to access and provides a steady stream of diversions that are just a click away. I think for some this becomes too much and they need to find a means to break the cycle of "This task I need to do is hard, I'll Reddit instead, that's easy and rewarding".

I've had to take a break from Reddit in the past because I was becoming disappointed in how I used my free-time. I never got further on any of my projects or hobbies—I just browsed Reddit on my phone.

When I'm at work I try to limit my Reddit consumption to mostly text-based or programming related subs. This way I don't endlessly fill my mind with memes, fun pictures, comics, etc and my browsing doesn't go from beneficial-diversion to procrastination-catalyst.
