I would say my brother. Both of us have extremely high IQ's, but through my life's fate I haven't really been able to rise as high.
Along with working full-time building our Data Analytics / Big Data business for our company, he is holding a 4.0GPA at Harvard and was invited to be a teaching fellow a few weeks ago.
In 11 months while heavily travelling between Florida and Louisiana and handling the sale/transfer of ShreveNet to it's new parent company, he took down every Cisco CCNA/CCNP certification and earned a CISSP and CCIE. In three months, he took down CCIE Storage, EMC and NetApp's top certifications.
He can play multiple instruments and can read music quickly.
He also knows a ton on home/auto/electrical repairs and micro-electronics.
He was also an editor for quite a few technical publishers for a while.
