In many matters, you simply cannot do it yourself. It would take too long to acquire the necessary level of knowledge and skills. But in many matters, you might be able to do it alone - whether it is accounting and recordkeeping, or preparing income tax returns, or developing internal controls and procedures, or establishing a valuation, or starting or restructuring a business, or setting out personal financial plans or making financial decisions, or a thousand other money-related matters. But operating on your own, without guidance, is like putting an addition on your house without the help of an architect, or carpenter, or electrician, or plumber, or painter. You could learn to do the tasks, but probably not with as much skill as the experts, and the years necessary to acquire the knowledge and experience would make anticlimactic the completion of the task. Even if you could finish the house addition within enough time to enjoy it, it might not be built well enough to stand up over time. Also, two heads are always, well almost always, better than one. If you are a smart independent self-starter, try this approach - do all the research, lay the plans, assemble the team if others could be involved, and then call in the CPA to be the quarterback, or at least your guide.
