Important things I've painfully learned:

- ALWAYS trust your gut, don't ignore it. But don't overreact either. Instead, cautiously do your research. THEN act on it.

- Also don't trust anyone who has a need for secrecy in their life about themselves. Especially when it pertains to the relationship you have with them. Whatever that may be. If they hide little things that shouldn't matter, they have issues you need to be aware of.

- There is a difference between being dishonest and having a bit of privacy in your life about some topics. You don't need to tell everyone EVERYTHING about yourself. Not all at once anyway. This is a delicate thing and is different for everyone. You sometimes set yourself up to untrustworthy people by disclosing your weaknesses.
