How do I pick a stock?

Okay, so after over at least 1 and a half years trading on the markets I've learned lots of things. I dont want to admit that because learning has cost me a lot of my equity.

Through learning I've discovered that patience in a stock is the best tool you can have. I find an entry point somewhere on the low side of the middle between the 52 week high and 52 week low. After taking my position, (only 1/3rd of total asset allocation to that ticker) I'll watch the stock plummet still.

Then, I'll put the other half of the 2/3rds remaining back into it again to lower my average.

My thoughts are simple, picking a stock is rather difficult sometimes, but it doesn't have to be. I pick a stock then stick with a stock until its green for me. Longterm trading has always been the best strategy, longterm gains happen when you stick with a stock, and invest over time incrementally. If you believe in a stock, put your money where your mouth is.
