Being an omnivorous technology generalist is punishing to start out as and lasts for years, but becomes incredibly valuable later. That's something I wish I could have told the prior me.
Come to understand: Being a generalist is not about "lacking experience to call yourself an expert." Touching on innumerable disciplines is itself a crucial skill that lets you operate in the real world with huge autonomy. Just know your limits. Most problems don't need specialists. Generalists are the ones that ***know when to call in the specialists and give them what they need***.
