Don’t feel inadequate if you aren’t lining your nest with the shiniest, newest things possible. Who cares what technology you use, as long as it works, and both you and your users are happy with it?
That’s the beauty of new things: there’s always a new one coming along. Don’t let the pursuit of new, shiny things accidentally become your goal. Avoid becoming a magpie developer. Be selective in your pursuit of the shiny and new, and you may find yourself a better developer for it.
There’s a shittier variation of the magpie developer: the one who keeps moving on to the next shiny object without even learning the fundamentals. They’re just in it to tickle their fancy, not to get things done. Stay the hell away from them.
