Some time we only think how to start but we never think about the action and the finish
So, Our time will spent with nothing better.
When someone already got they dream, We still try how to sleep...It's a far a way from the result.
For any kind of our goal, it must be a planning to do that, to minimize the risk but the most important than it, is the action.
We thinking without action, is nothing...
But We do action without thinking is maybe something..
So,,Don't be afraid, just do it what you want to do. The process is more important than the outcome.
