Once you get the basics, it should be fine. Just watch out when you take the boat out. There will be days you book everyone to go out, and then there's a wind in the wrong direction that will make COMING BACK IN difficult (leaving is easy). Don't do it. Be prepared to cancel, or just have drinks on the boat. IF you let your pride do the talking, I can guarantee you at one point you'll be eating your pride ... we've all done it, we either learn the hard way or the easy way and save a lot of embarrassment and $.
As you get more skilled, you can then step things up a little ... but slowly. It'll take a full year if not two before you're okay, and even then, docking is always going to need your full attention.
I agree on the recommendation above about hiring a captain for a day ... they will teach you technique you'll probably never learn on your own. I had a 1 hour lesson (for free when I bought my boat). I learned A LOT in that 1 hour. Made a big difference.
