Read everything you can find concerning sheep biology and hunting. Decide where you would like to hunt and study the sheep habitat and horn growth. Determining legality is a key component, and being a student of horn growth really helps with this task. Study and learn how wind moves in the mountains, also how thermals effect wind flow. Be mindful of shiny stuff on your gear and never wear sunglasses on your head, they reflect light that can be seen for miles. Learn to do more glassing than walking and try not to hike into an area when sheep are bedded, they have the advantage if bedded as often only their head is exposed. Much easier to spot them if they are up and feeding. Sheep can be patterned, as mentioned patience is often key, they will often feed in the same areas and return to safety to bed down. I like to creep near their feeding spots and wait for them to come to me. Overwhites and decoying can be effective.
Taking a mountaineering course would be a smart move, remember that if it is sketchy going up, it will be terrifying coming back down. Always conserve your strength and energy. Keep basic survival gear on you and don't be adverse to spending the night where you are when it gets dark. A sheep hunter's feet and mental toughness will be key to success. Pain and discomfort are all part of it, learn to embrace the suck. If you don't want to quit at least once, you are not hunting hard enough.
If you can find a mentor, that really helps, finding an older sheep hunter can often be beneficial. Sheep hunters are about the tightest lipped hunters there is, so finding one that can no longer hunt, which often means "on their death bed" can be gold. NEVER betray that trust, anyone that I ever share with would become "those I never speak to" if I learn they spoke of a place on the map.
I tread the high places, not to seek and find sheep, but seek and discover my own limits, hoping to maybe bring home a ram in the process.
Good luck on your journey.
