How to get over those roadblocks

There are two types of zones: comfort and courage zone. Comfort zone; represent all things in which you've comfortable with your family, home, close friends, college and library. You are familiar with all activities and people, you're safe and secure. But in courage zone, you've not familiar with; new friends, new situations and risks. There is growth and opportunity. Yes, there are risks and you cannot gain if you are not prepared to take risks. You'll never make new friends, know adventure and face a challenge if you can't take risks You will never overcome fear.
Of course you may fall several times trying to do things that you have never tried before but every time you fall, you learn and get closer to your goal. If you were afraid to ask a girl, you really liked, to go out with you. You were afraid, she would reject you. Well, one fine day some other guy from the courage zone did and you lost her. You were a lost opportunity to be with someone you really liked because you were afraid, If you are in comfort zone, you get no rewards simply because you never tried. No risk, go gain.
