Sometimes you'll hear people say that you can't love others until you love yourself. Sometimes you'll
hear people say that you can't expect someone else to love you until you love yourself. Either way,
you've got to love yourself first and this can be tricky. Sure we all know that we're the apple of our
parents' eyes, and that our Grandmas think we're great talents and our Uncle Roberts think that we will
go to the Olympics, but sometimes it's a lot harder to think such nice thoughts about ourselves. If you find
that believing in yourself is a challenge, it is time you build a positive self-image and learn to love yourself.
Self-image is your own mind's picture of yourself. This image includes the way you look, the way you
act, the way you talk and the way you think. Interestingly, our selfimages are often quite different from the
images others hold about us. Unfortunately, most of these images are more negative than they should be.
Thus changing the way you think about yourself is the key to changing your selfimage and your whole
world.
The best way to defeat a passive self-image is to step back and decide to stress your successes. That
is, make a list if you need to, but write down all of the great things you do every day. Don't allow doubts
to occur in it.
It very well might be that you are experiencing a neg- ative self-image because you can't move past
one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as
your primary task. If you think you're silly because you aren't good at math, find a tutor. If you think
you're weak because you can't run a mile, get to the track and practice. If you think you're dull because
you don't wear the latest trends, buy a few new clothes. But remember, just because you think it doesn't
mean it's true.
The best way to get rid of a negative self-image is to realize that your image is far from objective, and
to actively convince yourself of your positive qualities. Changing the way you think and working on those
you need to improve will go a long way towards promoting a positive self-image. When you can pat(拍)
yourself on the back, you'll know you're well on your way. Good luck!

Thirteen vehicles(車(chē)輛)lined up last March to race across the Mojave Desert, seeking a million
in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and
watchers knew there might be no winner at all, because these vehicles were missing a key part-drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push
to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just
proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance.
One had its brake locked up in the starting area. Another began by throwing itself onto a wall. Another
got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by
remote (遠(yuǎn)距離的) control. One went a little more than a mile and rushed into a fence; another
managed to go for six miles but stuck on a rock. The "winner," if there was any, reached 7.8 miles
before it ran into a long , narrow hole , and the front wheels caught fire.
"You get a lot of respect for natural abilities of the living things," says Reinhold Behringer, who helped
design two of the car-size vehicles for a company called Sci-Autonics. "Even ants can do all these
tasks effortlessly. It's very hard for us to put these abilities into our machines."
The robotic vehicles, though with necessary modern equipment such as advanced computers and
GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human
recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think
to wipe apple juice off her face, but she already knows that when there's a cookie in the kitchen she
has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced,
even months old, than any machine humans have designed.
