Keep your eye on the 'ball'

Concentrate on what you can do and focus your attention.

Once you have decided what your bottom line and how you want your life to be, focus your attention on it. Concentration is essential. Ask questions and look for the answers.
Refuse to allow other people to do your thinking about how something should be done.
Associate with people who will help you achieve your goals and coach and inspires you to success. Drop less important activities and people who bring you down.
Put your heart and soul into it. Create an overwhelming desire to materialize your dream. Focus your thoughts and actions in the direction you are heading.
Avoid dwelling on negativity. Think positive and abundance. Imagine, affirm and resolve to succeed.

Eliminate self-imposed limitations.

What you have achieved in the past does not determine what you are capable of accomplishing now and in the future.
Decide to make the changes necessary. A change in your perception about your potential will help tremendously in your pursuit.
Change your mindset about your limitations. Create an image of success and it will help build your confidence and esteem.
Think out of the box and think differently from how failures do. Self-imposed limitations are just excuses.
Playback your success recordings that are stored in your mind. Let that remain in your focus. You will feel more in control and adequate.

Take consistent action.

Even a small action produces its consequence. Develop the discipline to take even a simple action each day even though you are unsure of the outcome. Induce the attitude of positive expectancy and believe that your actions will lead to favorable results.
Fight the procrastination habit and develop a sense of urgency. Put in the hard work, the effort and finish what you started.
You have to work on your personal growth and your goals every day to create the momentum. You need to pay the price.

You need to work harder than the 'average'.
