Your first week with Claude

Don't try to apply everything. One move a day is enough — in this order, each step builds on the previous one:

D1

Install the Desktop app and turn off "Help improve Claude" in Settings → Privacy (module 04 · module 14).

D2

Fill in your Preferences: who you are, your tone, your requirements. 10 minutes that will improve every answer for life (module 11).

D3

Test a real brief: role + context + task + format on a current topic (module 03).

D4

Connect your first connector (calendar or mail) and ask for tomorrow's brief (module 10).

D5

Delegate a deliverable to Cowork: an Excel or a PPT produced from your files (module 05).

D6

Automate a routine with /schedule: a morning briefing or weekly check-in (module 05).

D7

Create your first Project for your most recurring topic, with your 5 best reference files (module 11).

📌 The success criterion At the end of the week, one simple question: did you get back at least 2 hours? If yes, keep going module by module. If not, revisit module 03 — it's almost always the brief that's off, not the tool.

A word from the author

Most people use Claude like a "better Google." It's not their fault — no one showed them the rest. This guide exists for that: to take executives from 10% to 100% of the tool's potential.

AI won't replace executives. But the executives who master AI will gain a decisive head start over those who ignore it. The difference isn't decided by the tool — it's available to everyone — but by the method and the rigor of implementation.

Try one feature today. Just one. Then another tomorrow. In a few weeks, Claude will become your best teammate.
