Successful people are those who are able to anchor their lives around a overriding vision, a dream that supersedes everything else, and then set achievable goal in line with their vision. Their vision in life may be to use their God given talents to improve the live of rural communities. To achieve that vision, they must determine what kind of help they want to provide for the rural communities. In addition to that, they need to have a real passion for people who live in rural communities. Without that passion, they would be overwhelmed by the setbacks they might face and give up eventually on their vision. With all of that in place, they would be required to set goal to achieve specific targets that will enable them fulfil their vision. The goal are therefore the link between their vision and its fulfilment.
You have to set goal that are challenging but which you can accomplish.
