Key wellness & productivity strategies (6 fixes)

1) Declare war on notifications (and use a VIP filter)

  • Turn off most notification alerts (e.g., news apps) unless you’re in roles that truly need them (law enforcement/journalism).
  • Build a VIP list (max ~15 people) so only the most important contacts get through even during Do Not Disturb.
  • Put key contacts into the phone/email VIP settings (e.g., partner, kids’ school, top clients, boss).
  • Mantra: “I deserve better than the default settings.”

2) “Kill the color” + hide the phone to break the habit loop

  • Switch the phone screen to grayscale/gray mode to reduce engagement and app-cycling.
  • When you need maximum cognitive performance:
    • Put the phone out of sight (ideally in another room), or at least far away/out of reach.
  • Rationale: even an idle phone nearby can reduce cognitive performance because the device draws attention even when it’s “off.”

3) Stop being a passenger—set MITs (Most Important Tasks)

  • Each morning (or the night before), pick 1–3 MITs maximum, not 17.
  • Write them down on paper (recommended):
    • Include a prompt like: “What will my future self thank me for?”
    • Writing boosts recall and sustainable motivation.
  • At day’s end:
    • tear up / rip off the page to avoid carrying unfinished-business guilt into tomorrow.

4) Stop multitasking—single-task to avoid “switch tax”

  • Treat “multitasking” as task switching, which costs time + energy every switch.
  • Principle: You can whole-ass one thing or half-ass two at once—never whole-ass two simultaneously.
  • Reduce unnecessary switching throughout the day.

5) Run a real focus sprint (structured deep work)

Use a step-by-step sprint:

  • Schedule it on your calendar in advance.
  • Outline the execution steps before starting (tiny steps with an execution plan).
  • Remove distractions:
    • phone away
    • only one task / one screen
    • turn off notifications
    • keep a “parking lot” notepad for interruptive ideas so you don’t chase them
  • Set a timer so you work with a clear finish line.
  • When done, take a real brain break:
    • no email, no scrolling, no inputs—just rest so you can sprint again later.

6) Respect your biological clock (chronotype peak window)

  • Focus ability varies by time of day; an “hour” isn’t equal for everyone.
  • Identify your chronotype (AM shifted, biphasic, or PM/night owl).
  • Find your daily 2–3 hour peak cognitive window and defend it for your hardest work.
  • If you’re not an AM person, extreme early-morning “hustle” routines can backfire (sleep deprivation → worse performance).
  • Optional tool mentioned: mychronotype.com (code: Dr. Sahar).

Overall theme

  • These fixes are about doing less grinding and optimizing less, but reducing noise so your brain can focus—and get your time/attention back.
