You may not know it but you are a gardener you plant seeds every minute sometimes those seeds are beneficial to your garden and other times they are weeds that choke the life out of your garden. The seeds are your thoughts and the soil or the garden is your very own mind.
We have a choice will we water and care for the thoughts we want to grow or will we instead have a garden of weeds each seeking to purchase more of our attention and mental resources only to return nothing for our effort except the same old experience we don't want to be followed by the same thoughts over and over again.
We have the choice and we get to choose the focus we place on thoughts we have. Ask yourself what am I planting? what thoughts am I watering? what thoughts am I fertilizing with my attention? Do they bring me happiness, joy, or closer to an experience I desire?
