How you see yourself determines what you’ll do. How clearly you see what you want to do determines what you’ll accomplish.
Your self-concept and beliefs about what you think you can and can’t do and so important to what you’ll even attempt. If you don’t think you’re worthy or capable you won’t even start.
And, the clarity and specificity you have about what you’ll do is the single biggest factor in what you get done.
If you have vague plans, you’ll have vague accomplishments.
If you have specific (grand!) plans and you’ll accomplish much indeed.
