Have you ever decided to do something, but you hesitated because you thought you were not well prepared?
In fact, you make things a little complicated. Listen, before you come to this world, before you were born, did Jesus or any god(I don't care) asked you, "Hey, little baby, are you ready to come to the word outside? It's dangerous outside here, are you ready, are ya?". I bet it wouldn't happen but in your mid-night dream.
Sometimes, you have to learn to make decisions without caring too much, the only thing you should care is time, time waits nobody. And if you did, the result is beyound anyone's mind, too risky? Come on, more risky then you are a human-bening, which live in China? Think about this, what kind of food do you think is safe to eat in our lovely country?
What's more important, we have to learn to face our risk in our life, as risk finds you with no sign. After many of this, we will learn to make ourself in less trouble, and solve troubles in a much better way. That's a journey we have to go through, that's a step of growing up.
Have you decided to do something yet not did? Do it, it's gonna be very "interesting". Good luck!
