If you are in a legal job, boring or not, I imagine it pays fairly well, and if it doesn’t, then maybe you should look elsewhere. I am not sure why you feel the need at this point to spend a year in Israel to learn, but you can also learn here, keep your job and still enhance your knowledge even if it isn’t full time. If you are really that interested in learning, a 9-5 job gives you plenty of evening time to study. To me, it doesn’t sound it’s worth upending your life, journeying into uncertainty that could easily distract you from your purpose for going. But may I ask, why is this your deam at this point in your life?
