In life, we all have regrets...things we should have done / anticipated that we did not.
We all have the ability to make the life of someone else brighter just by a kind word, just by reaching out when you know they are down. Never let an opportunity to show concern for others pass you by. You never know when one contact from anyone will make a big impact on someone else's life.
I know this all sounds maudlin, but this is not about anything I am going through personally, just an observation.
Now, go Vote and go forth and conquer with your goodwill!
