Whatever type of business you will choose, you don't need to think much about working on the business that you will run. If you keep asking questions and thinking without trying, you will not know the results. Talk less do more!
You're absolutely right!Many of us don't want to try its because of were afraid that after we try maybe it will end up into failing but as what you have said its good to try without thinking and asking questions so that you will know what will be the result and its up to you if you are going to accept it as a knowledge and experience.
