Many people think that they may need to go to college or on a training course to learn new skills to help them find employment, but often if it other skills that you need to improve that can help you land the position you have always wanted.
Social skills are often important in terms of working. It may be that you are going for a job that is customer facing. In this situation the employer will need to know that you can speak to customers in a polite and efficient way. Organisation is also often a skill that is called upon in many jobs. If you can show that you work in an organised manner, plan your day and have a system in which to file any documents then employers will feel that they can trust you to have responsibility.
If you feel that it is people skills that you need to work on then going to group events and attending networking events may help improve that and give you the experience and confidence that is needed.
