Entrepreneurship is hard. It needs unswerving discipline, and confidence in yourself and your business. Lots of people lack the opportunity to enjoy it. But for the few who are determined and ready to put in the hard work, entrepreneurship is the most fulfilling job, identity and lifestyle in the world.

Let’s look at 4 daily habits of successful entrepreneurs.

1. They stick to a routine

A day has 24 hours only and as an entrepreneur, time is the most valuable thing in the world. To get the maximum potential out of every day, successful entrepreneurs follow a strict schedule.

For instance, Elon Musk, the founder and CEO of SpaceX and Tesla, schedules his whole day in five-minute blocks and he breaks up his week, where on Mondays and Thursdays he focuses on SpaceX and on Tuesdays and Wednesdays he pays attention to Tesla. He splits Fridays between both companies.

2. They read a lot

Most successful entrepreneurs make learning a regular daily habit. For instance, Bill Gates, Microsoft co-founder, reads 50 books a year. As an entrepreneur, you need to learn as the world is continually changing, and the most impactful entrepreneurs create their profiles by improving their knowledge.

If your background is in design and strategy, as an entrepreneur you must have engineering and computer science knowledge to contribute meaningfully to your ventures. Examine your future goals and establish what skills and capabilities may hinder you, then start learning today to be ready for those roadblocks. For engineers and designers, that obstacle may be management, finance or project planning. Yours may surprise you!

3. They exercise daily

Yes, exercise keeps your body fit and the mind sharp, and it has a great impact on an entrepreneur’s long-term achievement. The reason is that it relieves stress and helps maintain a healthy work-life balance. Many successful entrepreneurs attribute their success to exercising and keeping fit. Richard Branson, the founder of Virgin Group, increases his productivity with daily exercise.

Don’t make excuses! Fitness and mental calmness are essential for a happy lifestyle. They’re the building blocks to your productivity for days, weeks and months. Find a sport, activity, or practice suitable for you and make it habitual by being responsible.

4. They stay positive

As an entrepreneur, you’ll face many challenges, but what makes you succeed is a positive and creative mindset. Every day. Being able to see things from a positive dimension means you can see interesting and unique opportunities others can’t see.

If you can’t remain positive, it’s time for a change. For instance, Steve Jobs started his mornings by repeating a simple mantra: “If today was the last day of my life, would I want to do what I’m about to do today?” If he answered this question with a “No,” then he knew it was time to make a change.
