Create and be attentive to opportunity.
There is nothing mystical about luck. If the individual desires an oak tree in the middle of their garden, no amount of praying, meditation or mystical ritual will manifest an oak tree out of nothing; plant an acorn in the soil, give the acorn attention, and the chances are high after a period of time an oak tree will manifest.
In recent weeks I have been lucky finding many coins and currency notes on the ground that inattentive, stressed and drunk people drop upon the ground in the dark. This luck has been due to a few years of practice of observation as I walk around, a fun challenge of spotting coins on the ground, and thus I have an eye of a hawk, my instinctive scanning of the ground creates the opportunity to find dropped coins.
In my garden is a shed, upon which the pine needles of a tree fall upon the roof, decomposing into a mulch, and little blades of grass are growing, seizing an opportunity to live in the mulch of the shed roof. In my local park the squirrels forage for nuts they buried in the ground, with crows shadowing them, the squirrel find the nut, the crows seize the opportunity to grab the nut. Feeding ducks, individuals encounter seagulls swoop in to grab the food even before it hits the water. Our cat Helix sits attentive in hidden places watching the birds feeding at the food station, waiting the opportunity to grab a careless bird.
Luck is neither random or mystical. Nature offers the insight that living things create their opportunities through effort and attention. I find my coins because I trained my mind to spot them, then I maintain a watchful subconscious attention for the coins. Some seagulls I observe create opportunities for food by stamping their feet in a rain dance on the ground to trick the worms to the surface.
There is an experience called synchronicity, a type of coincidence where an individual thinks or acts in some manner that appears to coincide with an event, for instance I think of a person and a second later that person telephones me. Whilst synchronicity is one aspect of the weirdness in nature, at the core is an individual who has acted either in thought or deed to make space for an opportunity to arise of synchronicity.
