Betting on yourself is the ultimate form of self care
Every season, TikTok gifts us a trend that feels more like a mirror than a meme. This time, it’s The Great Lock-In Challenge — a collective call to focus deeply from September 1 through December 31, to treat the last four months of the year as fertile ground instead of dead time.
And this one? I’m in. Not just because I love challenges (though I do — obsessed, really), but because I’ve seen what they can do.
Why I Can’t Resist a Challenge
For years, I’ve built my life by stacking challenges month after month.
There was the season I challenged myself to cut out debt. Another where I focused on fitness. The months I committed to business experiments, writing sprints, and yes — even just waking up at 5am every single day.
Each challenge carved away something small, but the sum of those choices? It completely turned my life around.
That’s why when I saw The Great Lock-In appear on TikTok, I didn’t hesitate.
