Your trustworthiness as a leader is vital to your influence and impact. Increase your trustworthiness, and your influence increases, but if there is even a hint that you cannot be trusted, your level of influence will decrease accordingly.
One way to bolster your trustworthiness with others is to get rid of hidden agendas. Do your best to be honest, transparent, and open when communicating and leading. You cannot control how others ultimately perceive you and your intentions, but you can control how consistent you are with eliminating hidden agendas from your leadership. When you are consistently and appropriately honest, transparent and open your trustworthiness will grow and so will your influence.
