Stage 1: Oh no, it’s too complicated I cannot possibly make it (gloomy face).
Stage 2: Hmm, I’d done this part before. And this one. And this one is extremely simple. I’ll do some research though on this last part. It’s still not clear how to approach it.
Stage 3: One or two hours later: Ha, it’s so easy-peasy. It's time to get some practical work done!
