Yes, we must see and identify obstacles but never allow the obstacle to be the deciding factor to not doing what we set out to do, that which is laid in our hearts. The Obstacle must never have the power to depress us and kill our vigour to realise our aspirations and goals.
No matter the size of the obstacle, we must always have the 'I am going to win' mentality and attitude...in other words: Faith. So work victoriously, focusing only on victory and marching straight to it, especially when we are certain that what we call work and business is in alignment with His purpose with our lives.
Remember that He made us for 'a special work' and this applies in all parts of life; be it business, work, society, community and life in general.
Most cancer survivors win the battle against cancer because of a choice to live life without cancer, to win.
