You can achieve success only by your knowledge and your hard work; you cannot feel the success just because you got the position to be on the top. By some chance if you have reached a top position, it is really difficult task to maintain the position without having knowledge and the experience to move forward or succeed in the required direction.
When you are not able to take the right decisions at the required positions you start feeling the difficulties of the position at the same time others will start noticing that you are not the right person to be at that position or authority level. People start ignoring you for your doings and the suggestions given by you.
If you have the required experience and then you occupy the position, you will work and take decisions in confidence, and all your actions are recognized and respected by others. You start creating goodwill and a real respect for yourself and your position. Everybody will be proud to have you as a leader at that level.
The best way is to acquire the required knowledge base and then climb on to the position.
