Why bother with Ethernet Cabling

Why do why bother with Ethernet Cabling.
I think there is a balance between doing it yourself and calling the professionals. If it’s a straight forward manageabe task and you have the correct tools and knowledge, why not. For example, I wouldn’t climb an 80 foot tower, pull and terminate 120 pairs of Ethernet cabling or try to terminate fibre connectors.
Working onsite and I was asked “Why bother?“ or “We’ll get someone else to do that”. Some people feel that some network tasks are too menial or beneath them. I’ve had some network technicians ask why I would bother doing ‘that kind of work’ when you have had various certifications.
There are many answers; I like the variety, I enjoy keeping my skills sharp, and the job gets done quicker. I find I can add more value to a design or install since I have physically done the work as opposed to just reading the materials. The bonus is that when I watch people do incorrect installations, I have more things to look for when troubleshooting problems.
