It's all about getting out there and practicing when it's a little breezy. You'll hardly ever have a perfect day with no wind down the runway (at least here in the SLC). You've just got to slowly build your confidence and you're probably going to sweat a little. There's nothing wrong with going up when conditions are a little crazier than you'd like to fly in. (No I don't mean that along the lines of flying VFR in IMC) If it is too crazy though you should take an instructor. Just keep in mind there's a difference between pushing/expanding your limits and being just plain stupid. Be careful out there!
