There's a variety of activites I enjoy, and I can draw energy from a lot of places. Some more than others. (note I don't know my type).
I think one of my favorite though, and is ultimately the most fulfilling (and gives me a lot of direction and purpose), is being in some sort of leadership position. I'd argue it's one of the most consistent sources for me. I have a lot of fun with it. I gain a lot of satisfaction from setting up things, teaching, plans, games, rules, etc. and watching it all go together. There's just something about it that is thrilling and gives me a lot of personal satisfaction. In a way, it's like building a machine, but it's invisible. People are either the parts, or the things that get processed. I love watching how all of this evolves over time. I.E. if there is some sort of tangible data or product that comes out of it I enjoy leadership even more. I don't always want to be in charge of everything. Just things I feel I can improve, have fun with, and I must feel like I will be able to do the job well and right. If I don't think I can do it, or I feel like my efforts are for naught, I eventually stop. I'm rather ambitious by my nature, and also perfectionistic so this sort of comes along with that.
I love listening to music. It allows me to connect with myself on non-verbal levels and feel things I normally otherwise couldn't. It can also be a springboard to imagining all kinds of stuff. Real or not, and I can get completely lost in it. If I do this too often the novelty of it starts to wear off, or it can be draining. Most of the time though, it's recharging and I enjoy it. It's sort of a focused solitude that I value a lot.
I get energized by having fun with good people. I'm pretty talkative and love sharing experiences, running around exploring, and overall enjoying each others company and having fun. I don't always want this, but when I do it's very fulfilling.
I get energized by doing nothing completely isolated from everyone. Just lying in bed all day, not doing a darn thing, ignoring all the things I have to do, and completely immersing myself in a sloth state. Do this to often and bad thing happen (and that is something I quite often seem to forget). Honestly though, anyone would get burnt out if they didn't recharge or get energy from different sources.
Can't leave out the internet. Then again, who doesn't love the internet, and who doesn't get energized by it in some capacity?
