I read a great article today, from the founder of a new startup called Foodspotting. The post is about her being able to clearly envision how things would work out at her startup, before she started it. It is a fascinating read and shows power and clarity of purpose.
When you have a clear vision of what you want from life, paths are created for you to get there. In isolation, the previous statement seems very abstract to relate to. However, you read stories like the one I have linked above, time and time again. It is not that these people get lucky, they just have a much clearer idea of what they want from life and are not afraid to ask for it.
