When running a solo business, writing about too many scattered topics disconnects your content from your products. If no money comes in after 3 months, you burn out and quit. You cannot buy more hours in a day. Your only option is to concentrate your energy on what keeps your business alive. Your content topics are structured using the Know — Like — Trust Content Funnel taught in the Writing to Sell coaching program by Cuong Thach, where topic themes are positioned specifically to serve sales copywriting. This model operates on a precise publishing formula: 40% Life Stories (Know) — 40% Core Craft (Trust) — 20% Conversion (Love). Finishing this 5-minute setup gives you the shortest path from content to cash flow, while locking in an intake filter that keeps your brain from burning out.

Preparation Before You Begin

Before defining your topics, make sure you have:
  1. Finished your Career Map (specifying: Who you are – Who you help – What outcome you deliver).
  2. Understood the strict boundary: Outbound topics (for your buyers) are completely different from Inbound topics (for your own learning).

Step 1 — Lock 2 Primary Outbound Topics for Your Audience

During the early stages, create only 2 public publishing themes to market your business and feed your cash flow:
  1. Life Stories (40% — Helps readers Know you): Share personal lifestyle, physical fitness, and mindset lessons centered around freedom (for example: endurance running, daily routines, calm living).
  2. Core Craft (40% — Helps readers Trust you): Share signature expertise, highlight painful client problems, and provide step-by-step solutions that prove your authority in your niche.
Important rule for the remaining 20%: The 20% conversion layer (direct offers and client enrollment) runs silently behind the scenes. You never create a public topic tag for direct sales pitches to avoid annoying your readers.

Step 2 — Set Strict Limits on Your Inbound Learning

Inbound topics are what you read and study to grow your skills. To avoid falling into the hoarding trap and feeling exhausted, limit yourself to 5 to 10 specific topics, distributed across these 5 life pillars:
  1. Health: Optimize your physical body to sustain peak mental performance (running, nutrition, sleep).
  2. Mindset: Cultivate stillness and energy in a noisy world (meditation, walking in nature, emotional control).
  3. Relationships: Build a circle of trusted friends and family to ground your independent journey.
  4. Business: Package your expertise into digital assets to unlock leverage and freedom (buyer psychology, copywriting, automation).
  5. Wealth: Manage cash flow cleanly so money serves your lifestyle, not the other way around.
The Intake Guardrail: Every book you read, podcast you hear, or video you watch must belong to one of these 5 pillars. Any information outside this list, no matter how fascinating, must be turned away to protect your mental focus.

Step 3 — Configure Your Two-Layer Filter

Once your topics are identified, configure them in your Digital Brain to activate your automated guardrails:
  1. Create 2 outbound topic tags: Create #life-stories and #core-craft. Attach these tags to drafts heading to the Share Station.
  2. Create inbound category tags: Create tags for your 5 life pillars (Health, Mindset, Relationships, Business, Wealth).
  3. Activate the two-layer filter: From now on, all raw data entering your system must pass through 2 gates:
    • Gate 1 (Scope): The note must match one of your pre-approved 5 pillars.
    • Gate 2 (Intent): You capture only when you have an active problem to solve that serves your outbound publishing themes.
Real-world example from Hoang Hxn:
  • Life stories: Hoang uses tags like #freedom-lifestyle and #running.
  • Core craft: Hoang uses tags like #solo-automation and #systems-design.
