Pick your mentors they are very helpful. One thing that I was fascinated by when I moved to the US was that people are always available to help all you have to do is ask. Don't feel shy, don't feel that you are cool reaching out to a random person and they will ignore you. People talk and like to help, and pay it forward. One of the biggest things I learned from my mentors when I went back to them and said hey, thank you for helping me out. What can I do for you now that I sold my company? They told me three words that have stuck with me,  pay it forward.
