10 quick and practical methods to increase your confidence:
Smile loads! Smile when you meet people and generally be happier even if you’re not feeling that way.
Learn from the past but don't dwell on that which you can't change. You could even ask yourself 'What was good about that?' for a great reframe of the situation.
Buy yourself some new clothes, get your hair done, treat yourself to something new. I know you won't need too much encouragement from me on that one!
Are you prepared for situations? Are you prepared enough to meet any challenge that may come up? Are you prepared for that networking event, that presentation, meeting someone for the first time? If not, get to it.
Play to your strengths. Expose yourself to what you are good at, at every opportunity. Improve your weaknesses and put a plan in place to improve them in time.
Don't be a people-pleaser! Learn how to say no to people, when you really want to. After you’ve said it the first time, there will be no going back.
Be in charge of your thoughts at all times. If you’re thinking negative thoughts, you’re probably asking a negative question or focusing on the problem rather than the solution. Change the question to a more positive one.
Whenever you feel stressed ask 'is this really important in the grand scheme of things?' If you're having to make a tough decision, ask yourself how each of the options affect the next 10 hours, 10 days 10 months etc. (I call this my 10/10 rule).
At the end of each day list your achievements and successes throughout that day. Acknowledging them before you ask 'What could I have done better?' is a great discipline.
Every morning when you’re in the shower, visualise your day as though it was already a success. Visualise success and the relevant confidence and it will be so.
