I always remember the film ‘as good as it gets’ and the lead lady turns to Jack Nicolson and tell him life is not the sum of all parts. It is a great line and I often think of it when in certain situations, indeed when in business dealings.
The need for ROI and added value is often paramount but some times, on occasions, the results are unknown and as such the quantifiables are un predictable and hence I consider the statement.
Sometimes its not worth it and some times it is. What you will always know, is that you had a go and sometimes the learning is the reward.
