‘Be a reflection of what you’d like to see in others.’
One of the main keys to be a successful leader is to do what you say others they need to do. For example, if you say everybody needs to be in the office at 5.30 pm, do not show up later. Consistency and coherence between your words and actions are the pillars of your credibility within the team and the organization.
Your colleagues will trust you when they see that you stick to your own rules, and even more, you believe on your credo and values, and you act according to it. Once you achieve success, your team members will become your followers, as they will desire to be like you. If you are successful with your own strategy, your followers will try to copy it in order to achieve success as well, and you will become their example.
There is nothing better that lead by example.
