Story: How Shadow got unstuck :)

When rated 1600–1700 in Blitz, I played daily, took no breaks, & became tired, burned out, tilted & unhealthy.

When I closed my account—from 14th April to 18th May—I played no Chess (except on CC at first).

After I returned, my Blitz rating rose from 1681 to 1904 in 13 days. I felt happier, healthier & refreshed, too.

That was when I realized you should work well, not hard.

In conclusion, a break may be helpful if you're stuck, worsening, or not enjoying something anymore.

PS: This means that sometimes, not working accelerates progress.
