Either you lead, or you follow. Sitting on the fence too often can be a reflection of your indecisiveness. Eventually, you will follow when you over-deliberate and get confused with too much conflicting information.

The future has a place for leaders, whether in the workplace, business, or your community. Step forward. Make a change. Do something different. Make a difference. You would be glad for doing so.

Time to, seriously, make and hold the lead! Swim on.
