Hard Work Does not Pay Off
This statement may seem counterintuitive and even controversial, but it is a direct consequence of the fact that programming and software development as a whole involve a continuous learning process. As you work on a project you will understand more of the problem domain and, hopefully, find more effective ways of reaching the goal. To avoid wasted work, you must allow time to observe the effects of what you are doing, reflect over the things that you see, and change your behavior accordingly.
In addition, you always need to learn more about software development in general and programming techniques in particular. You probably need to read books, go to conferences, communicate with other professionals, experiment with new implementation techniques, and learn about powerful tools that simplify your job. As a professional programmer you must keep yourself updated in your field of expertise — just as brain surgeons and pilots are expected to keep themselves up to date in their own fields of expertise. You need to spend evenings, weekends, and holidays educating yourself, therefore you cannot spend your evenings, weekends, and holidays working overtime on your current project. Do you really expect brain surgeons to perform surgery 60 hours a week, or pilots to fly 60 hours a week? Of course not, preparation and education is an essential part of their profession.
