For me, it was all a matter of timing (ie, having a farm of my own and the right mare/s)! I had always wanted to breed for both personal and hopefully “semi-professional” goals. I say semi-professional because, although I am an adult amateur and don’t do horses for a “career,” I take it seriously and don’t take breeding my mares lightly, although I recognize I am not up to the level of many, more experienced breeders - and I say this with admiration! 
I was an equine major in college and very involved in the breeding program. And as I stated, I have also been a very active and serious adult amateur with ambitions of competing at larger shows with my own, homebred and personally trained horses. So, with my dream farm finally in the works (literally), I decided to breed my first mare, who was retired do to an unfortunate pasture injury.
I am, at this very moment, expecting my FIRST homebred foal, due June 1! I am very excited about this! I am, of course, hoping for a filly… as this breeding was planned with long term goals in mind. I bred my mare to a stallion who I feel is not only a stallion of great performance horses (which I believe the “filly” has to prove herself worthy), but also of great broodmares. So I was thinking generations down the line when I planned this breeding, as I see it as the start of my dreams coming true – a small breeding program (I guess we all have to start somewhere). Rest assured, even if this foal is a colt, I will love him just as much; I’ll give him a good start and some good solid mileage, but I might decide to sell him in a few years – but we’ll see, as he will be my first foal. I am already thinking about next potential matches for this girl, although I have decided not to breed her this year, and instead wait until early spring next year. She is a very feminine and refined girl, so I look for a stallion with a lot of substance and bone, among other traits.
A couple years ago, when my mare was injured, I purchased my “dream horse…” well, I saw potential in her to be my dream horse, but I could only afford a two-year-old. Haha. When I was looking for a horse, I set out looking for both a performance horse and for a filly that had lines I was interested in breeding with down the road. So I set out looking for a mare I would (potentially – if she proves herself) chose for breeding.
Fast forward a few years, and she has more than proven herself thus far, in performance and mind! But of course, I’m actively riding and showing her, so breeding her is on hold. I am hoping to do ET with her in a year or two, but for now, that’s on hold (or at least the hubby says so).
For her, I will pick out a proven performance stallion with a great temperament! I prefer not to use an overly “modern” stallion. I like a little more substance, but not quite super old style either. That’s how this mare is – a good mix between old and modern. Of course I will also look for stallions that complement her high points and will hopefully strengthen her weaknesses. I spend lots (I mean A LOT) of time thinking about potential matches and researching stallions’ performance records and their offspring. So although I don’t have the quantity, I’d like to think I will produce high quality. I also love it (as it was pointed out in another post), when stallion owns can help with the matches – when they know what traits their boys pass on, what crosses well, and what doesn’t cross well. I believe a SO’s input can be a tremendous asset!
I guess in short, it was timing for me! And I have always had ambitions of breeding high quality horses that are amateur friendly, but professional quality. Even just one or two foals every year or two. In general, I look for stallions that compliment each mare individual, with great temperaments, strong work ethics, and performance records – I know… probably what most of us look for.
At this stage, for me personally, and although there are some super nice young stallions, I would prefer to breed to a stallion that has proven himself in upper level work. Similarly, my mares have to prove themselves first too.
In addition, because I am such a small breeder (just getting started of course, but with big plans) and both my girls are in MMB’s in a reputable registry, I will keep in mind the foal’s marketability going into the breeding. Although I don’t believe, IMO, a horse has to be in a certain registry or can’t be a cross to be a high quality horse; it is something I will keep it in mind for marketability. Of course I’d love to keep each and every foal I breed – and I’m sure I’ll keep “some”; the reality is I don’t have the time or the space to keep them all. And ultimately, I would like to make this “semi-professional,” so I do plan on breeding, starting, and selling. I am planning on hanging on to some of my foals until they are about four or five, started and then selling - and selling some as foals. I also hope, through my two current girls, to add another broodmare or two down the road. No worries though, I don’t have delusions of making money… I just hope I don’t lose too much!
