Nothing in life is impossible provided you never lose sight of your goal and are willing to be flexible at all times and totally dedicated to achieving your aims. Setbacks crop up at the most inconvenient times, but they give you the opportunity to make changes, accept new challenges and achieve your targets in ways you could never have thought possible.
Never give up, never lose sight of your objectives. Be ruthless when assessing your progress. Take chances when you need to. Everyone needs to speculate to accumulate. Go for it at all times.
