There are people who appear to be haunted by the words What if. What if I had done X instead of Y. What if I had got up the nerve to ask her out. What if I had made a different decision. What if I had paid more attention. The list can go on and on if we choose to let it.
But talk about a waste of time. We made decisions and took actions or failed to take action and decisions based on moments in our past. Those moments are written in stone and cannot be changed. Regretted or learnt from but unchanged forever.
To continue to play the What if game serves no purpose but to occupy our current moments in wishful thinking about some possibility for a more positive result. No matter what we think we cannot change the past it is beyond our ability.
We need to focus on creating our future with our actions right now. In the next moment it will be our past and so our future unrolls from a series of present moments. Don't waste them.
