It happens to all of us.. I remember once I was prototyping a big circuit with a bunch of chips and wires and everything and I spent an hour trying to figure out why nothing was working. I tore it apart and redid it twice, replaced chips, everything I could think of and I couldn't get anything out of it.
Until someone pointed out that I didn't have the chips' power wired in.
