Come on pfren lighten up. As you can see from my last line I am not being totally serious.
However, I was taught by a good chess player friend of mine to go for e4 openings because its tactics what is first needed to develop one's play, positional ideas (and even harder, the assessment of the possibility for a positinal idea to succeed) will come later with experience.
If you're better with tactics, play open positions, so 1. e4! (1. d4? results in closed)
If you're better with positional plans, play closed positions, so 1. d4! (1. e4? will get you murdered)
And if you're a sadist, play 1. Nf3!
