I find that younger software engineers sometimes take the attitude of: Why would I pay for that when I could easily just do it on my own? As they grow and gain more responsibilities that flips to: Why would I build and maintain something on my own when I could pay someone else a few bucks to do it? At least I feel I went through this change as I grew professionally...

So many things I am completely capable of doing on my own I simply don’t want to. I have better things to do. More valuable things.

Yes, build versus buy. The eternal question!
