When people say "Let it go," what they really mean is "Get over it," and that's not a helpful thing to say. It's not a matter of letting go - you would if you could. Instead of "Let it go," we should probably say "Let it be"; this recognizes that the mind won't let go and the problem may not go away, and it allows you to form a healthier relationship with what's bothering you.
Jon Kabat-ZinnLife on earth is a whole, yet it expresses itself in unique time-bound bodies, microscopic or visible, plant or animal, extinct or living. So there can be no one place to be. There can be no one way to be, no one way to practice, no one way to learn, no one way to love, no one way to grow or to heal, no one way to live, no one way to feel, no one thing to know or be known. The particulars count.
Jon Kabat-ZinnInitiate giving. Don't wait for someone to ask. See what happens - especially to you. You may find that you gain a greater clarity about yourself and about your relationships, as well as more energy rather than less. You may find that, rather than exhausting yourself or your resources, you will replenish them. Such is the power of mindful, selfless generosity. At the deepest level, there is no giver, no gift, and no recipient . . . only the universe rearranging itself.
