Value your own quirks. Everyone is different; your uniqueness is a much greater strength than just fitting in. Be proud of your individuality.
What do you like about your job? Write down 10 things, and then another 10. They're out there, so if you can't think of them you're not trying.
Congratulate yourself. Celebrate your achievements at work. Try to remember all the things you have done in the past six months and write them down in list form. You'll be surprised how long the list is.
Look at the impact you have. Think about what you have done recently that has helped others flourish; from a smile for someone who doesn't feel important to coaching a colleague through a successful project.
Liberate yourself. Write down how you would spend your day if you had total freedom. Now do it - or at least work out what to delegate or to stop doing, so that you can.
Listen out for praise. It may not be explicit or vocal, but a lack of complaints from a normally truculent boss can be just as good.
Take one step at a time. If it all seems too much, break your challenges down into mini-milestones.
Do something you enjoy. The rest can wait.
