In the UK you are required to record your hours for validation purposes. Most pilots take some pride in their hours as it is a historical record of what they have done, aircraft they have flown, where they have been and who they have flown with.
If you can't be bothered to record your hours in a way that gives you an accurate record of what you have done, why should anyone else care what you have done. No doubt your log will be of interest to a prospective employer as it will give an insight to your professionalism!
