Alright bud,
Head to Keel Lake in Achill. Will be there this weekend myself

Perfect flat shallow water for you to practice. Took me about 4 months (10 Sessions) to get up on the board. Dived the kite into the powerzone over a hundred times before it clicked.
Keeping the board pointed downwind was the biggest help also don't bother going on in marginal conditions to begin with.
