Maybe age? You are new? Or better than others at saying 'no'?
I would definitely not get too arrogant that you don't have this problem, just that you haven't been swamped yet. Haven't pushed this threshold.
On other end of spectrum, I've also encountered people that are always 'chill', and don't have this problem. But they are also not the people moving the needle, or being assigned the difficult tasks.
It's a balance. Sure, it's easy to not have this problem simply by not pushing yourself. But the ones that do push themselves and get overwhelmed, or have difficulties, are also not a good example.
