If you want to know more about Paul Rand, who is generally considered the greatest logo designer ever, I recommend:

https://www.amazon.com/Paul-Rand-Steven-Heller/dp/0714839949...

And his own books on design are all worth a read.

He did the classic logos of IBM, NeXT, UPS, Morningstar, Cummins Engine, CBS, Westinghouse, and lots more.

Paul Rand was different than many logo designers, in that he just presented a single solution, rather than letting the client pick from several. He worked out what he thought was right, and that's what you were going to get.

This is a pretty good book about Paul Rand, for the curious: http://www.amazon.com/Paul-Rand-Steven-Heller/dp/0714839949/

Go to art school, like I did. Hahahah. No, I'm kidding, don't. But do become educated about the past. Buy some books. I recommend starting with Paul Rand http://www.amazon.com/Paul-Rand-Steven-Heller/dp/0714839949 I love that book. I'll never let go of my copy.

The most important thing is not to focus too much on current trends. They're mostly bullshit that will be forgotten fast. The reason I say study the past is because everything old that has been documented is actually worth studying. It's "stood the test of time," if you will.

I think a lot of designers today focus too much on what's happening NOW, reading today's blogs and knowing the trends and whatever. So they go make things with an extremely narrow perspective and think they're designing when really they're retracing the only thing they know.

People don't know nearly enough on say, 50's modernism. Or the Bauhaus aesthetic. Watch the Eameses' films. Know the greats. Respect them. Broaden your awareness. Graphic design was huge before computers.

Then apply the broad ideas you absorb from that to the medium you're working in. That's my advice. There's no Stack Overflow for design. It doesn't work the same way as programming. You're not going to become a good designer by visiting websites.
