Letting go sounds easy, but as human beings it's probably one of the hardest things we'll ever have to do. It takes an immense amount of courage to be able to say goodbye to something or someone who meant a lot to you.
But, you can't keep holding on to things that make you sad. If you do, the misery will build up in your heart and start running through your veins until it consumes you. Don't let that happen. Have strength to say goodbye to who or what you used to love ~it's time to let go.
