You want to quit your stable job because you have an idea and a dream. You want to turn that into a reality and sustain it. But friends, family, or peers think you are crazy and are questioning your decisions.

As every entrepreneur knows, you don’t know if your idea will be successful until you try. So how do you get past the questions, fears, and unknowns when you feel lead to start a business?

It starts with a clear vision and a clear path. Without it, your dream will likely perish.

Here are four keys to help you move toward your goals amongst the doubters.

1. Put Your Goal(s) in Writing and Read it Often

Stay focused on your goal. It’s a passion and a dream for a reason. Don’t let the doubt of others cloud why you set out to accomplish this task.

2. Start Small

Don’t come out of the gate offering all you can, or you run the risk of losing it all. Most companies and ideas only improve with time and customer input. As you grow, you’ll eventually become bigger than your original vision.

3. Develop Boundaries with the Naysayers

It’s wise to listen to input from those you trust, even if it isn’t in favor of your dreams or goals. There may be legitimate concerns or questions you haven’t thought about. However, you should draw the line with individuals when they become a constant source of negativity or pessimism.

4. Have a Support System

Find a few people who are really good at encouraging you and will be there when you need them. They can be friends, family, or peers. A mentor – especially someone who has already launched successfully – you can go to for answers and wisdom would be perfect in your support group. Here are 3 ways to find a mentor.
