Do...
Start with yourself. The number one tip from all our contributors is: develop a clear picture of your interests, motivations, values and skills. Self-knowledge is the key to convincing employers of your value - you can only articulate what you have to offer if you know what it is. Also, very importantly, ask yourself where you want to be in the next three to five years. If you do not have a vision, you will accept whatever your potential employer throws at you. If you do, then good. The next step would be to look for a career path which will take you to where you want to go, in line with your vision.
