When you're feeling restless, motivated, or eager, you might say that you're "itching to" do something. But if you want to mix up your vocabulary, there are plenty of synonyms to choose from. You could say you're "craving" to do something, "aching" to get started, "yearning" for an opportunity, or "bursting" with enthusiasm. You might be "dying" to take action, "hankering" for a chance, or "fidgety" with anticipation. Of course, slang terms like "jonesing" or "fiending" can also convey a sense of urgency or desire. No matter what phrase you choose, the important thing is to channel that energy into accomplishing your goals.
