Time and Tide

Wait for none...
Only empty spaces remain,
To gaze accusingly at you.
Pointing a finger at the lost chance,
Smirking at the often used ifs and buts.
And when the end comes near,
You are again bewitched
By this visious circle.
Going ahead and then hestitating,
You get the byline of a coward.
What to do?
When bravery refuses to shake hands with caution.
