Now imagine if the one after that was a shiny? That would suck.
That's why I would never do something like that. The above would keep repeating in my head and I'd never give up.
That is what motivated me. I had to do 2251 soft resets to get a shiny starter. I wanted a shiny Cyndaquil or at the very least a Totodile but ended up getting a shiny Chikorita. Decided to take the Chikorita since I doubt I'm lucky enough to find another shiny starter anytime soon.
