When God puts love and compassion in your heart toward someone, He's offering you an opportunity to make a difference in that person's life. You must learn to follow that love. Don't ignore it. Act on it. Somebody needs what you have.
There is no reset button in life. You can't take anything back, and you can't undo anything. All of your actions have consequences, and the things you say and do today will have a lasting impact on the rest of your life. You have to understand that, and you have to be aware of it while making your decisions.
I've definitely learned a lot about this in the last decade. Losing many family members and friends has really opened my eyes to how quickly time passes and how important it is to show how much you love & care about all of those closest to you every chance you get. Even the stubborn one's because you never know when you may touch a life. Love & kindness rubs off on people! Try it! :)
