Have you ever come across the most brilliant idea and wondered why no one else had thought of it? Excitedly, you tell your friends and family all about it. Maybe you found a way to start a business that could change lives, pursue a lucrative career doing what you love, or fund that overseas trip you've been planning.

The only problem is, nobody else thinks so. You know that you have what it takes to succeed, but everyone else either shakes their heads or tells you all the reasons why it won't work. Nobody believes you.

While this is a frustrating situation many of us have encountered, here are two questions to consider if you're in this situation.

1. What patterns do you follow?

The past is the best indicator of the future. It's also why employers like looking at resumes to see if you're suitable for a position.

People look at your track record when they decide what you'll do next: Do you tend to follow through on a project, or do you stick resolutely to complete what's important?

For example, I know someone who is pursuing her PhD, and people think that she'll succeed based on her past successes. She's already accomplished other things that she set out to do in the past, so there seems little reason why this goal should be any different.

On the flip side, I know someone who hasn't had a job in years because he stopped working after receiving an inheritance. He keeps saying he wants to start a business.

Once every few years, he comes up with a new idea. Nothing has gone further than an idea. Is it a surprise that people don't buy into what he says?

2. What do your actions say about you?

People can only judge you by your actions, not your thoughts. You can have the most ambitious ideas running through your head, but if none of it translates to action, then it doesn't matter.

Many people say they're going to try out something new. They talk about their plans to partner up in a venture, travel somewhere, or change their situation. They might even do some research and dabble in a few things. But a couple years pass, and nothing changes.

If any of this sounds familiar, I've prepared a strategy to make your goals more concrete to both yourself and everyone around you.

The best way to make people believe you.

The most sure-fire method to make people believe in your abilities is having something to show for it. Having some sort of proof, whether it's a small win or progression, goes a long way towards building other people's confidence in you.

So how do you begin? By starting off with a concrete plan. If you want something, what are the exact steps you're going to take? Is there some indication that your plans will lead you where you want to go?

Occasionally, I receive emails from readers who tell me what they want to do and how others don't support them. So I say, "Sounds good. What are the steps you're taking to get there?"

Usually, I don't receive a response.

Instead of saying you don't want to do something simply because you "don't like it", or how you want to do something else instead, outline what you need to do to get there. This will put the validity of your idea into perspective and show people you're serious. If you've started working towards your plans and can show signs of success, even better.

When you have concrete results, it's a sign that your idea isn't another pipe dream. After all, seeing is believing.
