How you succeed is well explained in all posts above. I wish to add one additional point. As success is relative and competitive, there has to be failure also. All cannot be successful at a time. This is life musical chair race. even if all participate well, some will win and others lose. Obviously all cannot win.
When we start any work we should start with positive mind that means we should feel that we will be successful in that work and start then we surely get success
Success and failure these two terms come forth when people are competing among themselves. If they don't compete and be neutral to each other, there will be no remarks like success and failure.
