The eternal programmer's pendulum. One minute you're crafting elegant code that would make the gods weep, convinced you're a programming deity who should be giving TED talks. The next minute you're frantically Googling "how to center a div" for the 500th time, certain you've fooled everyone into thinking you know what you're doing.
That metronome swinging wildly between "I could rewrite the Linux kernel over lunch" and "I have no idea what I'm doing" is the quintessential developer experience. And somehow it happens multiple times before your morning coffee even kicks in.
