First of all understand why we have to choose some profession ? Because we are living in society. whatever service you are getting in world is because of some people's work. Think that you have wearing a cloths what if you have to make it your self. You are watching t.v. what if you have to make the T.V. yourself. You are eating foods what if you have to grow that in farm by your self . this can not be possible. So as we are living in this society we have to give service to society?
Now how will you choose what service you will give to society? Everyone has some talent. Find what talent god has given you. And if we have talent we automatically get interested in that work. Now after finding your talent think how can you serve people by your talent. If your mind is so calculating you can go to accounting. If you are so much interested in sport you can go to sport . just find your talent and interest and start serving people.
And you will become successful because you will never leave your profession. Because you are interested in doing that. You make your goals regarding your profession now. And you will get that because you will do anything for reaching that because you are interested in doing that.
WHAT IF YOU DO NOT CHOOSE PROFESSION WHICH YOU ARE NOT INTERESTED.
now if you see someone who is earning good money. and by seeing him you decide to do same work to earn more money. but you are not interested in. what will happen? you will not like to do that work. after some days you will leave that profession. and start new profession with zero. you will not get anything in life. everyday on your job or in your business you will think that when i finish work and go home? your peace of mind will go away.
Milk has more qualities than water. but if you put fish in milk than she will die. but in water the fish will grow well and one day will become bigger fish. so you find that where you should be. and if you choose profession what your forefathers had worked before you will automatically get that talent. if you change that your DNA will try to change. In our body there is an enzyme Histone in our body . it stores history of our forefathers. and it forces us to do what our forefathers have done in past. so their qualities improves generation to generation. now if you try to change that profession your DNA will start changing. and you will lost that talent.
