A good friend of mine told me that she is not Wonder Woman. She simply cannot do everything. I thought that was very bold of her to say - after all, she is a successful businesswoman, has a wonderful relationship with eve member of her family and was clearly very happy.

She continued to tell me that by understanding her strengths and weaknesses, she was better prepared to take on the world.

She knows when to turn down work because she is just too busy. She knows when to get or ask for help and above all, she knows when to say, 'I don't know how to do that, but, I will learn or find someone to teach me.'

It takes a strong person to do that. With competition amongst companies, colleagues and peers, it may seem too difficult to turn work and people down. But if you try to take on more than you can, you may not be giving your best in return. And if there is one thing my dear friend stands by, it's living up to any promise, deal or agreement she has made.

I couldn't agree with her more. I too will admit, I am not Wonder Woman.
