Insecure?

Have you ever feel this kind of feeling before? insecure...( I guess you have)
In my case, I often feel this kind of feeling...sometimes just for simple reason. But still, just sitting and wondering doesn't bring any help for you. Keeping go in, have strong faith and belief, no matter what  happen...all of them will be a great experiences that make you growth. I believe, we can't be wise by listen to other experience, we can't be humble by stuck in one place.
Am I ready to go out from my current comfort zone? Only one correct answer...I must ready no matter what.
