Best advice I got was not to trust people and the worst advice was to stay quiet when someone was being rude with me .

The best advice: Trust your intuition. If something doesn't feel right, there's a good reason for that and you need to be careful.

The worst advice: Don't tell management that what they've heard about you wasn't true, or they'll just get mad and fire you. Just agree with whatever they're saying, even if it's all lies. I probably would have been fired either way, but I should have at least told them the truth.

Best.. Choose the best for yourself.
Worse.. Get a credit card to build your credit score

Best - make sure you have a good quality bed and pair of shoes.
Worst - You're too emotional and sensitive
