The best way is just to listen and observe. Learn from the observations, learn from what you have listen. Sometimes that what you can only do. Think about stuff that happens around you... Find the opportunity to contribute. Listen and observe does not mean you are not clever enough to contribute. It just a way to find the opportunity... If we too rush, probably the opportunity is a bit slow and if we too slow probably the opportunity is fast!
So, better listen and observe and catch the opportunity straight away when it comes!!!
