Depending on what your site is about and how you promote it, you might not have any reason to include outbound links. I can think of some online stores that don't link out to anyone.
On the other hand, if you come across sites that you think are useful or interesting, and link to those from your own site, that's all you need to do to get outbound links. Ideally, that can make your own site more useful, and thereby increase the number of visitors who come back. You won't get that effect with just any old links, though. The links you collect should have some sort of logical relationship to why someone visited your site in the first place.
Well-chosen outbound links can add support for a search engine's perception of what your page/site ought to be ranked for. If your site were "three-blind-mice.com", a good collection of links to other sites about mice could help to convince the SE that, "Yep, this seems to be a good site if someone is looking for information about rodents.'" On the other hand, if your site were about nursery rhymes, it would be better to link to sites about literature, poetry, etc..
Keep your main focus on links that would make good sense to human visitors. If you do that and do it well, the search engines tend to follow along okay.
