Fear is not real as its a figment of your imagination telling your conscious self to hold back. i've gone thru close to 12 jobs and each one even though the company name is different and the environment and people may be different however after awhile it becomes all too familiar and the cycle continues.

I don't suggest to get a job which you are comfortable with , but get a career which you are truly passionate about. but hey ... that's just me =) work to live or live to work
