You are never given just one chance. Do not give up if what you have planted doesn't take root. Often another seed from someone else's garden will drop in and blossom for years.
Allow yourself a season of rest, as that is the way of all living things. Recognize when something won't thrive, prune off the dead growth, and let go of the cluster. Embrace each stage, and don't try to plant too many flowers at once.
Sometimes, the greatest gift is when what flourishes is not something you planted. Trust in sunlight, and water and the miracle of every seed... all will manifest in your garden.
