Here is the most practical way I know to approach laser:
**Step 1 — Understand what you actually need from laser.** Most people skip this and spend time solving the wrong problem. Write down your specific goal in one sentence.
**Step 2 — Survey the landscape.** Look at 5 real examples of it being handled well. You will notice patterns across them that tell you which approach fits your situation.
**Step 3 — Start with the minimum working version.** Do not build the complete solution first. Validate that the core idea works in your context.
**Step 4 — Test under real conditions.** Real usage always surfaces something the examples didn't cover.
**Step 5 — Iterate.** The first version is rarely the right version — plan for 3 refinement cycles.
Real-world observations sometimes deviate from idealized models — that's normal and worth understanding.
The part most people underestimate with laser: the gap between a working proof of concept and a reliable solution is significant.
