You Don't Have to Be Fast
A Mountain Biker's Guide to Riding for the Right Reasons.
A book for mountain bikers who show up on the trail not to win segments, but to feel alive. About perspective, presence, and why the sport matters most when the timer is off.
Why I wrote them.
Most owners doing $1M to $4M aren't getting the operational thinking they deserve. The Fortune 500 has seven-figure teams. The mid-market hires McKinsey alumni. Owner-operators get pitched cloud software and told to figure it out. The MBA Playbook for Small Business is the long version of that argument — and the operating discipline that closes the gap.
The Entrepreneur's Daily Altar is the other half of the same problem. Faith-driven owners run their businesses without the spiritual scaffolding the work actually demands. Ninety days, ninety pages, ninety reasons to stop pretending Sunday and Monday are separate buildings.
The hard part isn't reading either one. The hard part is running it. If reading is enough to fix what's broken, you didn't need a consultant. If it isn't, you'll know what to call us about.
