Have you ever thought to yourself, “Who am I to think I can do it?” Or far more atrocious, do you dread hearing this sort of judgment from your peers, family, and friends?

At whatever point this annoying voice begins murmuring in your mind, you can always turn your thoughts to these inspirational people like Oprah Winfrey, Richard Branson, Apple Co-Founder Steve Jobs, and Arianna Huffington. None of them were born experts of their craft, and they didn’t build their empires in a day, seven days, or even a year.

If you are confronting the festering fear of self-doubt, here are three tips to success that every hopeful entrepreneur should know.

1) Get Comfortable With Starting Small.

Motivation comes from momentum, even if it’s ugly and uncomfortable. –New York Times bestselling author, high-performance coach, and speaker Brendon Burchard

Indeed, even Tony Robbins, who is one of the most celebrated names in the motivational speaking industry, had only seven people appear at his first workshop. Now he fills arenas loaded with experts who run to hear his useful wisdom, as well as owning multiple organizations and having a net worth of half a billion dollars.

As with any objective in your life, you have to start with one little step and work your way forward. Thomas Edison was urged to give up after 10,000 attempts to create the lightbulb, but he rebuffed these comments with his infamous remark:

I have not failed. I’ve just found 10,000 ways that won’t work.

Despite what others around him thought, without tenacity and resolve, his invention may never have come to fruition.

The equivalent can be said for the top business pioneers over the globe. They are the ones who pushed past their apprehensions and insecurities, with fierce determination, reaping plentiful benefits for their perseverance.

2) Sell with Service In Mind.

If you don’t learn how to persuade, if you don’t learn how to get people to say yes, then you are doing a disservice to the world that needs you. –American entrepreneur, real estate investor, bestselling author, and coach Dean Graziosi

Dean Graziosi says that sales and persuasion are the oxygen of every successful organization on the planet. The issue is that numerous people are uncomfortable selling. He enthuses that the best approach to build your confidence is to quit feeling guilty for marketing your services.

Basically, you must cherish what you do so intensely that you feel you are doing people a disservice if you don’t get your clients to say “yes.” You must consider a lack of sales as letting your clients down.

Graziosi was able to go from little infomercials to running a billion-dollar business by focusing on the fact he is offering a service that betters people’s lives.

When you approach sales with services in mind, you will emanate authenticity and passion, inspire people to trust you, urge people to want to work with you, and at last encourage people to invest in you and what you have to offer.

3) Your Success Doesn’t Determine Your Self-Worth.

You can learn this from both Graziosi and Burchard, and it’s the most crucial element of all. You must be sure and have faith in your ability, regardless of the outcomes you get.

To reach the top level of success, your self-worth and identity can’t be inextricably attached to the outcome of any external goal you are working on. Otherwise, you will give up at the first roadblock, first disappointment, or first loss you experience.

Being a successful entrepreneur takes a great deal of work, a ton of vision, and a ton of perseverance. But anyone can have a flourishing, effective, and fulfilling career with the correct mindset, enthusiasm, and determination.

Dreams don’t just happen; it is your responsibility to take them by the hand and walk them into reality.
