Time is money. Yes, but how much money?
The "time is money" quote is so ubiquitous that we don?t really reflect upon its meaning ? or whether it?s true or not. Mathematically, we can see this quote as the simple equation T = $, where T denotes time and $ denotes money. But something is obviously missing: the units. How much time equals how much money?
When time is money is right
In theory, the quote, which refers to opportunity cost, is absolutely right. If you spend time on something, you could probably have made money by using this time in another way. But let?s have a look at the flipside. Instead of buying something, you can achieve its benefits in other ways. For example, you can design your website by yourself instead of paying a professional web designer. Or you can take the bus instead of calling a taxi. In theory, you can do (almost) everything by yourself, provided that you have enough time. In other words, every service or benefit from a product can ultimately be replaced by time. Whether it refers to opportunity cost or cost saving, "time is money" remains true.
When time is money is wrong
As you probably guessed, there?s something seriously wrong about this quote. Indeed, it assumes that time is a resource that is readily available. In the real world, time is a luxury, not a commodity. Whereas we can eventually earn (or loose) money, our time is intrinsically limited. The quote would be true in a static world where we are immortal. But in the real world, we evolve, and our environment changes constantly. In particular, almost everything we do has to be achieved within a window of opportunity.
The limitation of the "time is money" quote becomes obvious when we look at (IMHO) the most damaging of all entrepreneur pitfalls: trying to do everything by yourself. Successful ventures rely on many different skill sets. This is why successful entrepreneurs surround themselves with the right team. Applying bluntly "time is money" to save money will lead the entrepreneur to try doing everything by himself. As you know, even small projects require many components and skills. The project would take ages for one person to complete. Trust me, I?ve been there! At first it may seem a good idea to design your own business cards to avoid spending $200, to design your startup website to save another $800, and so on. Before you have time to take a breath, months have gone by, you don?t have a single customer, the market changed... and your business card sucks!
When I need some service and think I can do it by myself (and achieve the desired quality), I set the value for my time. This value depends on the opportunity cost and other factors such as the risk of delaying the project. As a rule of thumb, it should be at least the hourly rate of a badly paid contract that I can quickly get as a freelance worker. Suddenly, what appeared at first as a good idea to save money looks like a time-and-money sucking black-hole.
Consequently, the real question is: what is your conversion rate?
And the equation becomes: T = x$
