I am sure I am not the only person who have experienced or is currently experiencing the fear of the unknown..
In my own words, The fear of the unknown could be towards your career , the fear of the unknown could be towards your business , it could be towards your job , it could be towards your relationship ,it could be towards your marriage , it could be towards your family , it could be towards the society as a whole and it could be towards your life..
My own definition of "The fear of the unknown " is when you are afraid of what will happen in the future concerning any certain thing , for example you are afraid of what your future might be like with your career , you are scared that things might not happen the way you plan or expect , the fear that you might fail in that certain business you are doing or something bad will happen to the business etc..
Fear of the unknown is a problem which you need to deal with if you want to grow in life , fear itself will cause chaos for a person and limits their success and growth in life..
Fear of the unknown can cause depression , infact it almost made me depressed until I started to deal with it and avoid it totally..
Please do everything possible to make sure you combat the fear of the unknown, whenever those thoughts of fear are coming into your head , just chase it away and never allow it to stick to you , always believe in yourself and do not allow any negative thoughts to ruin you.
