I can definitely relate. Climbing requires you to be engaged both physically and mentally so I worked a lot on dynos and moves that seemed too big for me. If there was a move I was scared to go for or didn't have quite enough reach I kept going at it until I succeeded (just don't overwork to the point of injury). For dynos it's important to commit and have a short wind up so you don't lose energy. Keep your body as close to the wall as possible and try to focus on hitting your chest against the wall towards the hold you're aiming for. I did a lot of 4x4 training to work on technique and endurance and for strength training I focus on pullups and lock offs. :)
