Does this sound like the set of challenges you might be facing?

• I keep forcing myself to push through long blocks because some article said 90 minutes, but I can feel my focus quietly turn to mush partway in and the rest is just me staring
• I keep getting derailed by the same thing session after session and never seem to learn from it
• I try to power through a four-hour stretch of work in one go and the back half is garbage I end up redoing
• I tell myself I’ll do a solid focus block and then twenty minutes in, the second it gets hard, I bail to email or a quick "break" that swallows an hour
• Any meeting I put on the calendar for an hour reliably takes the whole hour even when the actual business is done in twenty minutes
