Anyone who has lived in Houston long, has contended with roadblocks. Roadblocks do not mean you cannot reach your destination. They simply mean you cannot get there by using the route you intended, and it is going to take you longer than you thought. Roadblocks just mean there will be a detour, but sooner or later you will get where you want to go.
Anyone who has ever had a dream they wanted to accomplish and has achieved it, has dealt with roadblocks. No one sees the fulfillment of their vision without having to overcome obstacles and take detours.
So when life puts a roadblock in your path, don't despair. Have patience, faith, and determination, and in time you will see the fulfillment of your dream.
