A fulfilling career is one where you feel happy to go to work, and feel that what you do is relevant and important. You may simply like working with your organisation and your colleagues, or it could be that you find yourself relating to your work on a deeper level. Whatever it might be, you should make sure you find work that suits you in terms of your interests and passions, so that you can enjoy it as much as possible.
You may not have found that work yet. If you haven’t, and you are actively seeking a new role, then be honest with your recruitment professional. Tell them what it is that you are looking for in a role, so that they can help you to find it. They will be one of the best placed people to help you get there, as they will have access to many different positions with versatile companies.
