Some general advice which helped me:
Use the wind and current to your advantage, or minimize its effect by the direction you bring your boat in.
Use as little throttle as possible to make the boat do what you want. A little burst from neutral into fwd or reverse then back to neutral is often better than letting it idle in gear.
Learn the prop walk characteristics of your boat and use them to advantage.
If the boat is doing what you want, do nothing. Having a little patience for the wind to bring the bow around, for example, can make things much easier.
Good luck; it does get easier.
