I do the same as kts. I don't see it as casting tho, it's a normal habit for me.
I use various color clothing for how I wish to effect my day. Bright colors. if I'm low on energy, earth tones if I need to be more grounded that day, black or blue when I desire a more protective energy, and purple when I am in need of extra creativity or need my intuition to be sharper that day.
My jewelry for that day is chosen in the same fashion based off of its material and what I have charged it with.
Sometimes I'll throw together a sachet of herbs and gemstones.
When I cook, I reflect on the ingredients and their meaning, and put thought and focus into the meal, especially if someone in my family is sick.
I'm always walking around barefoot unless outside. You couldn't keep shoes or socks on me as a child, or now. If it's warm, I'll go out and stand in the grass barefoot and ground myself, letting the energy of the day envelope me.
I live with a constant respect and awe for nature, and I am mindful of all energy that enters my body (food, drink, even air). It all has qualities that can aid you--body, mind, and spirit. Even the sun and moonlight that shines on you can be taken in to heal, clease, and protect.
Life itself is magickal, if you have the right mindset.
As for spells and ritual, it is only an occasional thing for me. I talk to the spirits and to nature itself more so than anything, not needing a reply. I don't really pray. I never felt comfortable with the concept. What will be, will be, and we make the most of what is now. If the future can be changed, then it is in our power to make that change with our own efforts made, be it through action, words, or magick.
