So this afternoon I found myself wasting my time scrolling once again (it happens less frequently than before tho). When I finally stopped my first reaction was to start regretting and worrying about that time I had just wasted. But then I paused for a minute and realized: time is already wasted and that I can't do anything to get it back.
So instead of beating myself up because of that I just got to my computer and started working. I actually did a fair amount of work and I'm now ahead of my schedule I posted some time ago in here.
So if you also find yourself in this situation, remember that you cannot reclaim wasted time, but what you can do is make the most of the time you have left. This also applies on a bigger scale with months/years wasted btw
