By astrological consultations, you cannot improve your career or your life because they are governed by destiny which at your age you might have by now understood the direction it is taking or taken. Perhaps you should read Bhagavatham or Bhagavad Gita to get answers to your question.
The future belongs to God and it is only He who reveals it under extraordinary circumstances. You can guess your future based on the omens of the present. And if you improve your present, what comes later will also be better. Forget about the future and live the present. God loves His children. He reveals to you the future only when the future that is destined is to be altered.
