Base your management decisions on a long-term philosophy, even at the expense of short-term financial goals.
A company needs to make money and system administrators need to keep their services up and running. This is a necessary foundation for successful work but it is far from sufficient. In order to be truly successful, you need to find a purpose that goes beyond banalities. A purpose that helps you and your people motivate yourselves to reach for greater goals. Once this philosophy is found and established, stick to it! From time to time it might cost you, but over the long run, it certainly is worth it.
In my case this long-term philosophy or basic motto underlying my work is committed to excellence. It means not accepting band-aids but always striving for sustainable solutions. This costs some time in the short-term when solving complex problems or implementing new services. But in the long-term we gain a lot of clarity and simplicity for our operators and achieve a high degree of availability for our users.
