The feeling comes before the decision
Most owners feel done long before they admit it. It shows up on Sunday nights, in the quiet dread of another Monday, in the realization that the thing you built now runs you instead of the other way around. That feeling is information, not weakness, and it deserves a real response.
Done is a milestone, not a failure
There is nothing to apologize for in being ready to move on. You built something that supported a family, employed people, and served customers for years. Wanting the next chapter is the natural end of a good run. What it deserves is a plan, not a Monday-morning impulse to call the first buyer who ever expressed interest.
The first step is a number
The practical starting point is unglamorous but clarifying: find out what your business is worth today, and what it could be worth prepared. The gap between those two numbers is your decision expressed in dollars. Sometimes it says sell now. Sometimes it says spend a year and sell for far more. Either way, you are deciding with facts instead of fatigue.
