Pick a strategy and stick with it.

Different people use different methods to pick stocks and fulfill investing goals. There are many ways to be successful and no one strategy is inherently better than any other. However, once you find your style, stick with it. An investor who flounders between different stock-picking strategies will probably experience the worst, rather than the best, of each. Constantly switching strategies effectively makes you a market timer, and this is definitely territory most investors should avoid.
