Let me start by saying that if you chose to open this posting and read it, that is a good sign that you are on the right track and your heart is in the right place. You have already moved from the realm of unlikely positive outcome to likely positive outcome. You have identified making someone's day as an intention in your life and that kind of intentionality is a real key to accomplishment.
Proverbs 18:1 says,
"An unfriendly man pursues selfish ends;
he defies all sound judgment."
It is in the pursuit that our judgment is magnified.
So I may leave it at that for today. To be friendly and to desire the good for someone else today will move you far down the road of being a blessing. When you wish someone well, it is communicated in your attitude, your words, and your deeds. you cannot help but be an encouragement to all who are receptive and in need.
