How can I express 'think' or 'thinking' in Chinese?
Examples:
I will think about it and answer you soon.
I'm not thinking about anything now.
I can't think clearly.
Please think about it and let me know the answer tomorrow.
Why do you always think I am lying to you?

Thanks for your help everyone, I know that this idea of think will be a few different words, so the more variations the better :)
