If we only did what was comfortable, we would never make any progressions. Challenge is part of growth but if you are your first obstacle, then you will never even try. No matter how ludicrous, never say no to yourself once you remove that impediment then you can start working out what you need to do, if you have the experience or skills, then getting down to complete the application or if you don't have the skills then what can you do to either acquire them or demonstrate you can pick that skill up quickly in the new role. Finally, make sure you read the application and provide them with the information they need to make it easy to appoint you or invite you for interview. The number of applications I see without any reference to the role they are applying for is really disappointing, so make sure what your application says is appropriate.

Keep your mind and eyes open as there are are so many opportunities

I have been very lucky in that I have almost always been given a role (or applied for one) that I have enjoyed in HMRC (or earlier departments). If you show that you are keen to learn and willing to listen, then you will find that opportunities will present themselves to you and you will progress in your career. When I was told that I would have to undertake taxes training in 2005, I was horrified. Having been trained in National Insurance and done various management roles, I thought that tax would be just too hard for me and that I wouldn't pass the exams. However, I committed wholeheartedly to the training programme. I studied hard and passed all the exams first time - even though my daughter was still a baby so I was constantly exhausted as well as having to travel to London once a week for 18 months for my tutorials!
