NBA legend Shaquille O'Neal has received a lot of challenges in his career as a basketball player. However, the A-star player revealed that one of his career lessons in life is never waste a moment.

For O'Neal, time is of the essence, which is why he was very particular on never wasting a moment. In a post from Complex, it revealed that O'Neal is known for being a man that knows all trades. He is famously known for being the star and the jack-of-all-trades.

For O'Neal, every day is a day to invest and do business. He did not just focus his time in one direction and on one career but he expanded his wings by venturing into business and investing his resources as well. 

The Big Aristotle's constant presence is his biggest strength on the business front. Whether he's starring in commercials for Buick and Gold Bond, pushing Shaq Soda on his co-stars of Inside the NBA, or quietly owning 10 percent of all Five Guys burger establishments, Shaq never wastes a moment without being involved in some sort of business venture, according to the same report.

It stands to reason that O'Neal is not alone. Being an NBA player himself, he knows the challenges and the competition that constantly shadows the NBA and his co-stars know it as well. Even Kobe Bryant, LeBron James, and Carmelo Anthony have ventured into the business as well, as reported by Jobs & Hire.

Shaquille O'Neal also understands the importance of using wits, talents and skills in the business. He makes it a point that each day is never wasted and that each day is a new day for business opportunities as well as the expansion of his business portfolio.
