I wish I knew the answer to this, but my head is like a can full of monkeys screetching.
I bought a pair of light bulbs for my automobile, and realized yesterday that they're the wrong kind, since now there are low and high beams, instead of the single kind. So then I had to figure out if the regular store would take them back from the chain, since I live in a grid-locked city, and wish to be in the opposite part of the city.
Making the mistake of going on the internet showed me so many kinds of bulbs, I don't know where to start.
What I could do is look at an objective source(notice I didn't say "should") and take their advice.
My solution to the calm my mind, is to realize what's happening, and log on and start a thread, or continue an old one.
Maybe someone will humour my condition and share their compassion.
