Prioritize your time. Turner calls attention to the total 168 hours in a week.
"Your job takes up 40, your sleep takes up 56, and you are still left with 72 hours to build your business," he said. "You need sleep. You need food. You have kids. However, you don't need Netflix. You don't need CNN. You don't need the two hours and 57 minutes per day you spend staring at your smartphone."
A few ways to maximize your time include possibly waking up earlier or eating fewer meals in restaurants and more from the microwave or slow cooker.
Zone in on your vision for the future. According to executive coach Linda Townsend, you can readily establish your startup mission long before you turn in your notice at your full-time job. Start by asking yourself big-picture questions such as, "What contribution do I want to make to the world or to my business?" Townsend told Inc.com. Next steps include making a list of your role models and the characteristics in them that you most admire; listing your core values and definition of success; and turning these insights into a personal mission statement.
Focus on daily imperative action. Whether you're working 9-to-5 or have unlimited free time to pursue your startup, locking yourself in a room for a month and emerging with a multi-million one-hit-wonder is not the way a business gets built, according to Turner. "It's not enough to just work hard. It's not enough to work hard every day. It needs to be imperative work, done daily," he said. The work can't consist of non-urgent or unimportant tasks like checking e-mails or yet more phone calls to share the same ideas with people who aren't stakeholders. "You only have so many hours to work on your side business outside of your job hours, so you better make them count," Turner noted.
Establish a routine of healthy habits. According to Townsend, some simple self-care habits are essential if you hope to survive the demands of becoming an entreprenuer: get 8 hours of sleep each night, exercise for 20 minutes each day, do something creative or fun each day and connect with the people you care about.
Keep your friends and family. Instead of figuring you can devote 100 percent of your time to becoming an entrepreneur and worry about the personal relationships you leave behind later, have a plan for personal time, too, says Gillies. "You don't have to give up your life in order to build a business," he said. "You'll need to have support of your family, friends, spouse and children. Create a schedule that includes them and work diligently to stick to it. Doing so in the beginning will create the foundation for the future of how you operate."
