Its important to remember that the internet amplifies experts, they get a big stage. What you see in tech are lots of very smart people in a very tight bell curve. Very smart compared to the general population. But in comparison to each other there is difference, but not as much as you think. Its easy to say don't worry about it. So i will add. Remember, even the experts only have time for at best 1 job at a time. They have lives to live too, make sure you live yours.
