The point I'm making is, don't waste your time on useless mickey mouse shit, because in the real world nobody cares that you've read SICP, or that you understand how loeb works, or that you've written your own parser.
The point you seem to be making is that you do not have the capacity do anything else than Swing GUIs in Java and limit yourself to this. Parsers are used pretty much everywhere and I don't think you've read SICP.
Actually, I think I have been trolled.
