How many times did the light bulb go off in your head? Afterwards that thought might have caused a couple of sleepless nights as the possibilities became limitless. And then, after another while, the dream dissipated. It went back into the ether from whence it came.
A few months or years later, somebody else did it. They snatched the idea out of the air, and now they are reaping the benefits. The benefits that you caused you all those sleepless nights. Oh, the irony! Imagine what might have been.
Imagine if you figured it out, put the wheels into motion, and did the hard work to bring it to life. Now it is too late. What was left undone, or in this case never begun, has been done by another.
That idea might be gone, but all is not lost. There are plenty of other ideas floating around out there. There are plenty of others that are floating around in the beautiful brain of yours. Let the sting of the lost opportunities be a reminder. Let their lessons permeate every atom within your being. The next time an idea magically appears, you will know what to do. Figure out how to make it work. Get those wheels into motion. Do the work.
Genius begins great works; labor alone finishes them. -Joseph Joubert
