1. The people in your team are worthy of your investment and development. If you think training is expensive, or that if you train people, they might leave, consider what may happen if you don't train them. Don't let it be your organisation.
2. As we approach the end of the year, spend it looking forwards, asking not what you did wrong or should improve upon, but how you are going to spend the future making a difference. You cannot change the past, only learn from it.
3. Before you judge others, try to put yourself in their position i.e. walk in their shoes for a while. Whatever they are doing or saying, there will be a motivation for it. Try to understand others better with your empathy.
4. Never make important decisions when you are emotional. If you do, then once that emotion passes, you will have a big mess to undo. Count to ten and wait until the emotion passes over.
5. If you lead a team, remember to tell them when they've done a great job. Don't just be known as the bearer of bad news.
6. Leave your personal and your work issues on the correct side of the door. Don't take troubles home with you only to take things out on your family - it's not their fault. Try not to let personal matters affect your work - everyone already has a lot to deal with and it just makes thing harder for all.
7. Remember to strike the right balance between work and home life. No-one ever laid on their death bed wishing they'd spent more time at the office. If you die, the organisation will replace you. Your family cannot. And they love you, the organisation does not.
8. When you achieve greatness in your work or a promotion, remember where you came from and how you got there. A humble leader has people walking the ends of the earth to follow them and to help them. An arrogant leader just has more enemies to look out for.
9. Be careful of social media - what you wrote 5 years ago may still get you fired. Don't write anything that you wouldn't say to someone's face and only write nice things. Keep the nasty stuff inside your head where it belongs.
10. Don't help others and expect to get something in return. It's just like you shouldn't lend money to friends expecting to get it back. Help people because you want to and not because they will owe you something later.
11. Think of all the best leaders that you know and try to emulate the best bits in each of them. We all have faults, so never try to exactly copy or replicate another person, just focus on their good bits. See feedback from others about what you are not so good at.
12. You spend much of your life at work. Figure out how you can make your role interesting and enjoyable, so that whilst you do get the job done, it's fun. You may also live longer.
Have a wonderful Christmas and very prosperous 2018!
