I hear you there. That's what makes it a sort of puzzle. Trying to lay out all the traces without crossing them can be difficult, especially with larger boards. That is why many professional boards are multi-layer. The free version of Eagle can support up to two layers of traces, which allows some traces to go along the top and others along the bottom. Sometimes this is necessary. Take the design I've attached, for example. This is probably the smallest board I've ever designed. It would have been impossible for me to lay it out without using the top layer (red) as well as the bottom layer (blue). Both were necessary so that I wouldn't cross traces. You may find the need to create multi-layer boards as you design more and more complex boards, but it's generally a last resort. Always try to put the traces on one side, but if you can't, then move on to the next layer.
EDIT: Apparently AAC only allows up to 97.7kb EAGLE files, so I'm having to use a temporary file storage service. Here's the board design: http://temp-share.com/show/3Yg8bj4Px
