Tell people when they did a good job, and mean it.

I'm not saying to gush over, but telling someone, "hey, you did a really good job with this, I like <thing>" seems to go over well with practically everyone. Even senior, domain experts like to be appreciated.

If you ever advice a person on a solution: follow up! Most people don't catch all of the bucketload of information you throw at them when they ask for assistance. Having a followup provides a convenient place for them to ask questions on stuff they forgot. I usually use this as a time to say good job (see above) and also ask what their next phase is going to be. Plus, following up lets you know if your advice was useful or not and helps you understand things more too.

If you every get advice from someone else, follow up!

Most of the respect I enjoy in life, both professionally and personally, comes from being generally appreciative of the people in my life. Turns out, people generally respect those who respect them.
