First, we need to establish the fact that people who predominantly use their left hands are south-pawed people. And a lot of things are special to them, without demeaning the right-handed folks.

Left-handed or sinistral people wonder why the world is oriented towards right-handed or dextral people. There is no answer to this question, however, do not try to switch yourself or your child to being dextral. Being sinistral is not a bane, neither is it a defect. Most African parents try to switch their wards to being dextral when they discover they are sinistral.

The good part of the gist is that being left-handed has its own advantages.

1. The most likely to pass a driving test. Statistics has it that 57% of left-handers pass a typical driving test while 47% of the right-handers pass a driving test
2. They can make more money. Most educated, diligent and hardworking left-handers have the tendencies to make more money than the other.
3. They are the fastest typists. “Left-handed typists can type up to 3,400 words on the standard QWERTY keyboard, which compares very poorly with 450 words for those using only their right hand. Just remind your colleagues that your typing is probably better than theirs because of this innate gift you possess.”
4. They have better problem-solving skill. “It must be a coincidence (or is it?) that the last five US Presidents (except George W.Bush) have all been left-handed. From Nobel Prize winners to Mensa members, lefties certainly dominate the world much more than their 10% share of the population would suggest. Looking at Mensa stats, the figure of 20% of its members being lefties certainly suggests that they are more intelligent.”
5. They are better at a sport. Look no further, Messi, Maradona, and others are the few football icons that have their names in the sands of time.
6. They excel more in creative arts. “Sinistrals are more likely to be successful than the dextral in music, architecture, and art. They have some pretty solid proof, too: Picasso, Leonardo da Vinci, and Michelangelo were all lefties. Add in Albert Einstein and Beethoven, and you have a great pedigree. Make sure your friends know this when you have your next burst of creativity.”

It is scientifically proven that your right-hand is controlled by your left brain, while your left hand is controlled by your right brain (there are juicy traits on the right brain, not as more on the left brain though)

So, start making use of your left hand or otherwise.
