Life is a chance in many directions ,the better and suitable direction we choose the better it is.We are suggested at many things ,but the way we consider the suggestion is what matters.

What I am trying to tell is ,there are many opportunities life provides and they are completely open but we don't know which one to choose. Hence we stay confused who we are .

Each and every opportunity is interconnected. Either getting to be an engineer or being an doctor or an banker is an opportunity.The opportunities doesn't stop, it continues. 

An Engineer can create medical equipments and machines for doctors and doctors can keep engineers healthy.Its just about solving problems to each other

Choose a path to solve a specific problem in a best way possible.
