Need to realize.

If our eyes were behind, the behind would be front and the front would be behind. This is because what is before our eyes is front.

Yes it is we should always see ahead and not behind its of no use repenting for the past instead do something good for our present and future. :)

Look ahead to shoot ahead.Not the other way round.

I will fear than.

It's true and important that look always in front (present and future) not behind (past)
