Re: In the moment....transitioning into another technique
You must learn the forms first. Learning how they don't work, and why, is just as important as learning how and when the do work.
For now (about the next year or two depending on your own personal growth) don't change technique unless a teacher tells you to.
You can not force your Aikido, it is going to take time. Do things in their proper order and you'll be all the better for it. Rush things, and you'll end up knowing half as much as you could.
Take it easy is my general advice, accept difficult uke's and learn from them. Teach your ego to let go.
