It is efficient to reinvest everything into a growing business. It is also a concentration risk that most owners would never accept in a stock portfolio.
Two statements, not one
The first step is simply preparing separate personal and business net worth statements. Many owners have never seen the personal one in isolation, and the exercise itself is usually clarifying.
Make drawings a policy, not a reaction
Irregular owner drawings damage both sides: the business cannot plan its cash, and the household cannot plan its investments. A defined monthly drawing plus a periodic surplus distribution rule solves both.
Build the second base deliberately
A personal portfolio funded systematically, held outside the business and independent of its performance, is what allows an owner to take considered business risks later. It is not a lack of confidence in the business; it is what makes confidence affordable.
