GOOD JOB!!! congrats on your first meet, which is always the UGLIEST!! timing lifters, nervous gitters- your got that one out of the way and ready for more.
I dont know what you placed, but it doesnt matter, you PR'd, remember the mindset that the whole meet is on for JUST YOU!!
You place doesnt matter because, everyone is a winner- that sounds cheesey but is true, I always say that "you dont fail NOT getting the desired result, you FAIL not trying" - you tried and did great.
Now its time to write down your goals where you can see them and attack new PR's, keep up the training.
