Only play for about five minutes at a time at first and then gradually build up the amount of time each day. This small sessions can be done multiple times per day. Make sure to wipe the excess moisture from the areas around the cork because that’s where it soaks in and causes the wood to expand, which leads to cracks. You have a Greenline, so don’t really have to worry about cracks, but better to be safe than sorry…

Don’t worry. You’ll be fine. I was in your exact situation back in the day and I had way more fun than the others my age. Congrats!
