Sometimes, we spend most of our lives preparing for something.. We put-off a lot of life risks because we think we're still not prepared enough; thinking that we will be more ready next time.. next month.. next year..
Some say that it's not necessary to get all your bases covered before making a move on your life because it will just give you a false feeling of preparation. You think you got it all prepared for all possible turnouts but when you actually move, it's still different than what you are expecting then boom you get disappointed. No matter how much you read and ask about it, you won't know something unless you actually try it. Just prepare as much as you can up to a certain extent and let your courage follow through.
