One can orient at Einstein.
Einstein performed very bad in his first school in munich but much better in the school he visited later.
And Einstein is an idol for me. Not only because of this fact. Einstein had an awesome way to explain difficult to understand things very plastically and on a simple way, so everyone was able to understand it. Also didnÄt he judged people bad for not knowing something nor did he made fun on such persons.
I hope my english is good enough for you while the grammar NaCl doesn't speaks german, french, C, C++, Perl, PHP, Turbo Pascal, Shell, Java, Delphi .... :-)
