If your business is growing and you have more things going on in your business, you have less and less bandwidth to understand and anticipate the challenges that you are likely to face.
Why does this tend to happen? Well, in my experience, what tends to happen is as the business grows and goes from strength to strength, you have more volume coming through the business; there’s just simply more things to do and when you’re a smallish business you tend to have functional responsibilities as the Managing Director.
The more work that happens, of course there’s more to do within finance, operations, marketing, sales, and whichever bits of those functions you work within your time gets absorbed into those areas.
