You cannot afford to allow the challenges of fear, or the baggage of your past to kill your passion for success, neither can you allow what people think of you.
Being passionate in fulfilling your goals are often referred to by many others as being aggressive, or being proud.. I am here to tell you; shut your ears to the gainsayers while in pursuit of your goals.
Your passion is that which motivates you to overcome the obstacles, and challenges that associate with success. Kick those obstacles, and challenges to the curb side and pursue.
