Letting go of bad habits, and practicing new ones, isn't always easy. Habits are incredibly powerful because over long periods of time they end up dictating the ways in which you live your life. Since entrepreneurs have nonstop days, jam-packed schedules, and little time to their selves, every minute--and ever habit--counts. 

This is why it's incredibly important that entrepreneurs stay aware of the habits they have, and the ones they lack. Building a business is consuming, and at the same time, founders need to stay clear-headed and focused. Which is why entrepreneurs should practice these three life-changing habits that these successful entrepreneurs swear by.

1. Take time to meditate every day. 

Practicing meditation daily is probably an uncomfortable idea for most founders. Startup life is go go go. It's all about efficiency, putting out fires, and staying on top of a nonstop workload. So, taking time to sit in silence every day may seem a little absurd. Which is probably why you need it the most. 

Mediation can create peace in the chaotic life of an entrepreneur, even if only momentarily. More importantly, research has shown that mediation has plenty of mental and physical benefits, which is why so many successful people practice it every day. 

Jack Dorsey, CEO of Twitter says that he wakes up every morning at 5:00 am to meditate. LinkedIn's CEO Jeff Weiner also swears by mediation. He says that he takes time out of his schedule to practice daily meditation. Oprah, who also meditates, has said that her practice of meditation is one of the most impactful things she has done to accomplish her incredible success (and billion dollar net worth). 

2. Get enough hours of sleep.

This one kind of seems like a joke, but sleep is incredibly important for brain function. Since the schedule of an entrepreneur tends to be out of the 9-to-5 norms, it's imperative that you prioritize sleep. This habit not only makes sure your well rested and well functioning, it can also help you create barriers between work life and home life. 

Arianna Huffington is a millionaire, successful businesswomen, and she is also a sleep advocate who publicly speaks and writes about the crucial importance of sleep. She says that sleep is a performance enhancer. 

In an interview with Fast Company, Arianna Huffington said, "The irony is that a lot of people forego sleep in the name of productivity but, in fact, our productivity is reduced substantially when we're sleep deprived." 

3. Have a schedule that keeps you on track every minute of the day. 

Even the most organized entrepreneur's day is all over the place. Running a company means having to be in charge of everything and everyone. You not only need to make time for your job but for your employees too (and probably investors, clients and a whole plethora of other people). 

This is why having a specific schedule is so essential to successful entrepreneurship. Gary Vaynerchuk is a huge advocate of this. "I wake up at 6 a.m. Literally, every day," Vaynerchuk said in an interview with Business Insider "For me, every minute counts, so my schedule is planned down to the second."

Planning down to the very second may be a little extreme, but you get the point. It's important that every hour (or minute, or second) of your day is accounted for. Waking up with a recognized plan and time structure for your day inherently keeps you organized, efficient, focused and productive. And these qualities are the makings for every successful entrepreneur.
