When people or situations no longer serve your growth, it is best to let go.
Close that door and turn around and see how many other doors are waiting for you to explore.
Be willing to make changes in your life, either by letting go or by letting in something new.
Be open to the New!
Do not fear it. Rather, embrace it and make the best of it, because it is your choice how you are going to perceive it.
Have a wonderful day :)
