Success Formula 1 building Computers Working with Computers Being at peace with myself while driving I think that about covers all of it...
I love the noise of the train, the one that you can hear because the tracks aren't aligned 100% accurately. But nowadays, there is no such noise, or at least there is no such noise where I usually travel by train. ( From 0:00 to 0:06: https://www.youtube.com/watch?v=qPjm7VsuImw) I just love that noise!
one thing that makes me feel satisfied is finishing top 5 in the nascar iracing series races. (competetive because the winners get to compete for pro) sometimes i spend hours running laps just to get a rythm going and get used to the car. Also making tiny adjustments to help my tightness/looseness. I get no financial gain from it though...but people have gotten rides in real nascar series from iRacing itself (K&N series, Nationwide, Arca)
Making music with my friends. Whenever we just start improvising something and it turns out sounding really good, it just makes me smile like an idiot
I love being alone in my room. Endless time, endless internet, endless Skype calls. No really, had a Skype call that went for 200 hours once.
What makes me feel good: driving cars (I mean REAL cars with powerful engines), playing guitar, carrying games in Dota 2, making things work in C#, crashing cars in BeamNG, eating delicious, junk food (I know it's bad), having sex and many others :3
The smell of high octane gas being burned, burning rubber, brakes, and clutches. The bwwwWWWWAAAAAp sound when a derby car takes off for a full track shot. Driving any rear wheel drive in snow or mud.. bubble butts
Things that make me feel good: Turning my speakers up really loud for 10 or so seconds. Best time is when a plate fell of my desk from the bass. Made me feel so awesome. Neighbors probably disagree though. Having a totally ridiculous and hilarious conversation with friends. Lovely planet, its so satisfying and happy. The last level of Dyad (eye of the duck). Best played in a dark room late at night when you are feeling slightly insane/hyper due to being tired. My eyes were watering due to all of the colours.
Seeing the suspension bob up and down in racing/driving games. Damn, do I love that feeling. Loud music LAN with buddies Being able to spend a whole day in a 3 cylinder diesel tractor doing whatever the hell I want
Search youtube for "London underground song lyrics" and its the first result., I would link it here but due to the language it contains I would probably be banned. All I could think of when reading your post which leads me onto: "people mentioning the smell of underground makes me think of the song: london underground"
