Where I am going with this post is that if you think you have an idea that will help you achieve what you are after, run with it. Do not be afraid of failure. Do not stop when people tell you it is a stupid idea, because if it is truly a good idea, you will here that it is stupid many times.And finally, believe in yourself, because if you do not believe in yourself, why would anyone else want to believe in you?
Think about the person who first came up with the idea of the railroad. That guy must have been told his idea was stupid a million times.
Thomas Edison tried over 2000 times before finally creating a working light-bulb.
