It may become quite depressing to read blogs, listening podcasts and work with professionals. You are constantly reminded that you should know that you don't know anything. It is comforting to know that others knew the same but knowing that is still disheartening, you know. You know what I mean.
What will make your life much more cheerful is keeping the state of blissful ignorance of this modern and ever changing stuff. What good can come out of taking on many emerging ideas? Half of them will be forgotten and buried within a short time and you'd never guess to avoid wasting your time on the doomed one. Being a mental coach potato will save your nerves, time and dignity. When technology will settle, one can always read "In 24 hours" or "Step by Step" book or wrestle a training course out of the management. Follow the job security guidance and you will be safe for the rest of your time.
