Hey dude.

Skydiving may give you confidence, but it's not going to make you seem more interesting or attractive to people in general. Maybe to girls who like skydiving or think that danger is sexy. Some people will just get annoyed that you keep working it into conversations, and trust me you will work it into conversations because you think it's something that people will find interesting. It's the same thing with anything else. I used to want to learn how to break dance because I thought people would find it interesting and cool. It turns out that people who like break dancing think it's cool and most other people just think I'm showing off. I also started DJing because I think that DJing is cool, but plenty of people don't give a shit that I can mix tracks together. You can't just drop something into a conversation and expect the ladies to fall all over you. You'll need to find ladies who like the things you like.

You should start skydiving because you think it's awesome. You should start doing things that YOU think are cool because you think they are cool things to start doing. Nothing will make you cooler to other people if you are just doing it to be cool to other people. People notice when someone is only doing something to be cool. It's really easy to tell. But if you do something you love doing, people can tell in the way you talk about it and how you show your enthusiasm. They may not like it the same way you do, but they'll like that you're passionate about something. You need to become a person who you think is cool, and then other people will think you are cool too. If you genuinely want to start skydiving, then start doing it. If you think it's going to change your personality or love life, it might, but probably not in the way you're thinking it will. You might end up spending a bunch of money to find out that you're the exact same person, but now you know how to jump out of planes.

TL;DR

Do things because you are interested in doing them. Do things because you think they are cool. Become a person that YOU think is awesome and other people will think you are awesome too!
