This is a hard question but an important one, what do you stand for in life, quality? Professionalism? Leadership? Entrepreneurship? Added value service?
Have a think about what you stand for and ask yourself, do you show that in your everyday career and if so how do you show that?
Then look at how you can make yourself that brand and show others what you stand for and why they should use you and your services above other people.
Try this and anyone that has success, please contact me as I would like to hear about your experience.
