Advice needed

Im a teen and I just did my first climb tonight. It was a 300 foot cell tower and I scaled the entire thing. I loved it and I want to keep this up. However I am a bit concerned considering I did not feel much fear while climbing, and I did not feel as much of a rush as i though i would. Dad was a skydiver and tells me that its in the blood to push the limits when it comes to stuff like this. Any advice on how I can keep myself from pushing the limits to far?
