It’s kinda sorta stoicism, just phrased in a judgmental, dismissive way, that is also pointlessly and rather toxically gendered. It’s close to the minimum amount of helpfulness “advice” can possibly have.

Being done with stuff feels good if your reward system is working properly. Other than that, while you can have “inertia” issues getting started and that feels kinda stressful, procrastination tends to get stressful too, after a while. At a certain point you’ll just have delayed the gratification to fit in some more worried and often unsatisfying faffing around.

Since pushing through whatever seems to work for you and make you feel better, I would focus on that instead of nonsense about not being macho enough.
