When you wake up, you should make it a practice to assess how you're feeling. And if you feel your mind asserting itself, make a choice right then to instead connect with your Buddha nature, your spirituality, with God. Say a mantra or chant. I say, "Rejoice and be happy, sing and be happy, awake and be happy." Or you could say, "I am filled with abundance and light. " Whatever works for you and is consistent with your practice.
This sounds like a little thing, but it is important to get your day off on the right foot, right from the start. Even though I meditate every morning, starting perhaps 15-20 minutes after I get out of bed, that's enough time for my mind to take me down troublesome paths. My meditation of course dissipates all that negativity. But why put yourself through that for even 15 minutes?
We were not put on this earth to constantly worry and be fearful, anxious. We were put here to partake of the light and bounty of creation that is all around us, to be sustained by the love of God/our Buddha nature within us, and to make the world a better place in whatever small way we can.
It was revealed to me years ago that my only purpose in life was to offer myself and others joy. And I offer myself joy by cherishing each moment, grateful to be alive; to be in touch with the positive energy, the faith, in my heart; to release all desire that my life be different in any way from the way it is right now at this moment; to be aware of all that I am grateful for; and to love myself unconditionally and have compassion for myself.
Note there is nothing in this list about being successful, or making money, or the other attributes of the understanding of joy and happiness that our culture forces on us. The things of this world are not our source of light, of joy.
This truth is also evident from what was revealed to me about what I need to be happy: to offer myself and others joy, to be in touch with loved ones and friends, to respect my mind, to respect my body, to be in touch with nature, and to live within my means. Again no mention of material things or things of the carnal world. Rather, by having the intent of living within my means, I am rejecting the felt need to acquire always more things in order to be happy.
And I offer others joy by doing what will be of benefit to them, whether through my writing, my composing, or my actions throughout the day. The one exception being evil ones. It is not the purpose of a Buddhist to offer evil ones joy. See my post, "Evil - How Should a Buddhist Respond?"
So tomorrow morning when you wakeup put a purposeful smile on your face, and say, "Rejoice and be happy, sing and be happy, aware and be happy." Make a choice. Follow that up by looking yourself in the mirror after you get up, smiling, and saying "Good morning! I love you," (what's called "mirror time"). These practices together with morning meditation will provide you with the spiritual strength to withstand the challenges you will face throughout the day.
May you experience peace and happiness.
