Consider how much weight a logo gives a business:

And look how easily one is made!

Say, for instance, at random, that you are a French egg deliverer with warts.

My impromptu egg-guy logo here utilizes a recent trend:  make a primitive sketch, as rapidly as you can, being vivid and daring in concept.  In other words, right-brain thinking meets left-hand drawing!  This wild, seemingly unskilled trend celebrates and often draws on the primitivism of cultures that peaked before the industrial revolution.  Remember, the goal is to try for the crude appearance both in content and in presentation.  Here, crude content includes the wheels that are impossibly attached; crude presentation describes the imbalanced shapes (i.e., wheels again) and the gritty, unpolished lines.

Yes you do!  You do need a personal logo.  And no, I didn't miss your trendy underline brushstroke there.  Speaking of which, I have recently seen several examples which define the ups and downs of what I call the Understroke.

What is wrong with the following logo?

Need help?  Here's a hint:

Answer:  your mind sees this particular one as a frown.  The Understroke:  tricky when not done by professionals.  I don't know how they got this wrong-- NCS is no small company. 

The question we must ask here is:  What is / was the original intent, or purpose of the Understroke?  It was to add an aftertouch of emphasis...like an artist signing a masterpiece....  To create an air of freshness, spontaneity...to give life to a design, logo, or word.  The understroke is typically of a rich texture:  i.e., crayon, chalk, paint brush, or lipstick. (Isn't the Avon logo underlined in red lipstick?) We want it to be warm, generous, and zesty.

The NCS logo above is doubly flawed:  The Understroke is in itself boringly symmetrical, adding zero life or spontaneity; plus it is centered perfectly under the words.  Stiff and regimented like a Nazi.  Also consider the blue box in regards to its contents:  the "meat" of the logo is also boringly centered, annoyingly large and forefront:  this provides no contrast between [space occupied by logo] and [unoccupied space].  Result:  tightness... a smothered, confined feeling.  Lastly, what possessed the graphic artist here to abandon the rough brush-stroke / crayon etc feel and rather plunk down a slash of smooth edges which taper to a fine point.  Now it looks like a set of steer horns.  Not only is the frowning logo mad at you, it is going to gore you.  Was this naturally made?  I don't know of any writing instrument or paint brush that tapers to a pinpoint at the ends while swelling to a broad line at the center of a stroke.  Yes, the "understroke" trend here has hit a dead end, its original thinking being exchanged for no thinking.

If you please, just one or two more quick examples of good and bad understrokes.

The irony is obvious.  As is the continuation of the steer-horn mystery.  Why not this obvious alteration?

Finally, observe one competent logo artist's confirmation of my notion that the simple presence of a horizontal bow is subtly viewed as a smile or a frown:

Now as for your own quest for a personal logo, there is really no How-To.  I can only offer landmines to avoid (above) and a few avenues to try. 

One idea:  One or few letters are better logo material than whole words and names and phrases and sentences.

Remember the Frigidaire logo?  A big blue F with a wide crown on top.  As for another "F", the Formica logo cleverly followed the above rule (big, distinctive F) and simultaneously went around it (small letters for the whole name "Formica", tucked under the large letter F):

Lesson:  Get known by your first name.  Or your last name, your initials, or a word made out of your name in a creative way.  Example:   My initials are JVO.  Boring.  Yet my last name is Irish, starting with O'L.  Can we use JVOL?  This is the kind of brainstorming you may try.  As for JVOL, it does sound neat when changed to J-VOL.  Let's make a bogus conglomerate named after myself:  J-VOL Industries.  Here is my resulting logo: it incorporates images of a globe, the letter J, rifle crosshairs, and an eyeball....  In short, the kind of corporation that James Bond would sneak into.

Notice the impact a personal logo can have:   It can give you market presence, power, and respect.  Every aim of the megalomaniacal webpage author, scheming Amway merchant, and perhaps-- even you.
