I cant second this enough. I echoed a lot of the same enthusiasm initially when getting into crossfit-style exercises but have slowly realized that heavy barbell/weight exercises is not that great for 5x a week training. I used to wear myself out to the point that my joints were aking so much that I had to take 1-2 weeks off just to come back to my old volume lifts. Its very easy to get too enthusiastic and it hurts more and more the older you are.

This and physical risks is a common problem. You feel great and keep pushing yourself harder. Without experience it's a pitfall one should be aware of.
