I just finished Steven Pressfield's pocketbook called "The War of Art." (See Required Reading.) This slim volume is very powerful and is a must-read for all small business owners. From hard-fought experience, he concludes that there is one thing that prevents people from achieving their dreams. He calls it 'resistance.'
You feel resistance as fear, envy, negative self-talk and 'helpful' comments from 'friends.' Essentially, to overcome resistance, you need to follow your own intuition and fight against what you perceive as reasons not to. I know upon reading this, that you will instantly think of five reasons why you shouldn't try a new business idea or product. In fact, most of them are reasonable. They may not be true, but they are reasonable. That's resistance.
Many small business owners lurch from fad to fad only to be disappointed when they realize that no one can dictate the one right 'magic bullet' for you. You need to do the hard work of developing a strategy. I use MindMaps to develop strategies for my small business clients. I recommend this tactic to you.
First, start by reading the book above and then sit down and create a MindMap of your business strategy. The map will provide tangible evidence that your plan is right for you, regardless of what others say. That's a good feeling when you're leading a parade of one.
