One important thing that I’ve learned over the past few years (I’m still, young, so I still have a lot to learn ), is probably this: when some design isn’t working after fiddling with it for half a day, it is worth while taking your mind back three or four steps, or even just deleting it and starting all over. This is something that is really hard in the beginning, because every design you make or code, has probably numerous hours put into. But once you’ve mastered the “throwing away and starting all over”-thing, it will save you a lot of time and frustration!
