Gratitude, like faith, is a muscle. The more you use it, the stronger it grows, and the more power you have to use it on your behalf. If you do not practice gratefulness, its benefaction will go unnoticed, and your capacity to draw on its gifts will be diminished. To be grateful is to find blessings in everything, This is the most powerful attitude to adopt, for there are blessings in everything.
I love the balls-to-the-walls rule-breaking approach the Beatles had in the studio (which I emulate), although I don't try to make my songs "sound" like their songs. But every time I crank a knob of some piece of equipment, or plug an instrument into the "wrong" amp/effect, I am channeling the Beatles.
Pain happens, but suffering is optional. When pain comes, make use of the experience, but do not wallow in it.
When you accidentally place your finger in a flame, it is supposed to hurt just long enough for you to pull it out.
If you think there is value in keeping it there, you will be a crispy critter. Pain is a minor element of life, unless you are indulging it.
Then it becomes suffering. Get the message and then get on with your life, which is far more about joy than sorrow.
The people who are successful are those who are grateful for everything they have. Giving thanks for what we have always opens the door for more to come, and ungratefulness always closes the door.
Anyone in a state of seeking can never be happy. Only those who are constantly finding are fulfilled. And finding is not something that happens to us - it is something we do.
