I am 27 years old. I was preparing for government job for last 2.5 years but could not able to succeed mind is always diverting here and there. Negative thoughts are always pouring on my mind. I could not able to concentrate properly. Unnecessary thoughts always break pace of my study. Smoking is another factor I think that affects my study. . Masturbation becomes compulsion for me especially at morning hours and when I was alone. Plse give solution.
