Oscar Wilde's famous phrase "Be yourself. Everyone else is taken" isn't just literary muse.
For "Shark Tank" investor and business mogul Robert Herjavec, it's a mantra.
Success requires periodically checking in with yourself, Herjavec writes in his recently published book "You Don't Have to Be a Shark: Creating Your Own Success."
In the memoir, he shares tips on how to make the most of your career.
Here are Herjavec's seven ways to know you're on the right path:
- You feel comfortable in your own skin.
- You feel no need to impress anyone about anything.
- You have no problem concentrating on what needs to be done in both your private life and professional career.
- You manage personal situations honestly and openly, without lies or exaggeration.
- Your inner voice is quiet when you are with others whose company you enjoy and value.
- Your muscles are relaxed and you breathe easily and normally.
- You feel good—about yourself, about your life, about all you have achieved and all the things you plan to achieve.
Of course, you may not identify with every one of Herjavec's seven markers.
But focusing on improving areas of your life in order to meet those goals is what helps you grow, Herjavec writes.
"Plan on being a lifelong learner. Because you need to be," he writes. "The path to success is rarely straight and short."
