designing like a pro..?

i hate assignments. i mean who doesn't? especially for my case, designing is like...you have to think, and think, and think just for the right concept. last two days ago, i was having a conceptual design practical class and we're supposed to hand in our assignments by week 7. so, before we hand in our assignments next week, we're supposed to show our designs to our respective lecturers. the title was ' plane to shape transformation '. a hard assignment where we have to crave our brains till midnight just to change some simple shapes into something else. you might think it's easy but it's not. it just sounded easy. but anyway, as i was saying, we're supposed to show our work to our lecturers, right? well my lecturer is quite nice. when he sees our work, guess what he said? he didn't scold us, but what he did was like shooting us with insulting words like ''..what kind of drawing is this? it looks like the primary school student's drawing. you're no longer a primary school student you know. you're a designer! and as a designer, you have to draw professionally and bla bla bla...'' well of course he's not saying that to me but i can hear what he said to my other classmates who showed him their drawings. well...what he say is kinda right but, not all people have such great ability to think and draw so well. you know, there're people who joined my course without knowing how to draw or knowing more about computers. see..? well..i still hate this subject. this subject makes my head really pain..but i don't have any choice but to take this subject. now if you'll excuse me, i'm kinda hungry now and i wanna go eat something but don't worry, i'll be back!
