"Beast mode" "Positive vibes" "Good energy"

These are all terms for that feeling we shoot for when we go out, try to pick up girls, make friends, etc. While I'm usually capable of tapping into this, it leaves me feeling drained afterwards, and it seems like I'm a different person afterwards to anyone who met me while I was in that mode. I started following this stuff because I'm naturally shy and pretty quiet, and want to change that about myself. I'm not really the type to try bringing home different girls every night, I had that phase and it's great, but I'm looking for a partner in crime these days. The "one" so to speak. (I know, abundance mindset and all that, trust me, I have it, I'm just a lot more picky about who I give my time to lately.) Like I said, I'm naturally pretty shy and quiet, and unless I actively try to overcome that, I revert back to my default state. However, I had a eureka moment. I came to the conclusion that if you dont actually go talk to people whenever they're around, you'll never find the girl that sparks and keeps your interest. I've made huge strides in that department, I've gotten over the largest part of shyness, and am working on my conversational skills (this is the hardest thjng for me.) Yeah yeah, I know. Read the books, apply the lessons, etc. Ive read a few books, but honestly this subreddit is more useful imho. Also, I feel like the best conversations I've had have flowed organically, I wasn't following some guideline.
Anyway, I got a little off topic. How do you guys keep that energy going? Or better yet, how do you keep it in reserve, easily tapped into when needed? You can't always be "on," right?

Also, I wanted to say, this group is supportive AF, and I love it. Its really rare to find something like that on the internet, especially when everyone is anonymous. This is my first post here, but I've been following and reading for a while now.
