Good, caring friendships are one of the foundations of a healthy life! Friends are the source of strength and knowledge when you are down. Friends can get you connected to opportunities and help you brainstorm ways to solve your problems.  If your friendships are based in superficial things, like alcohol, drugs or materialism, look for new friends. Go to places that represent your deeper interests.      If you feel your friendships are out of balance because you give more than they take, try to work on communicating better with the negotiable ones, and dump the selfish ones (if you can't avoid them, try to limit contact with them and say 'no' more often).      Spending time with people who are driven and work hard can be a positive influence on you. You can still be friends with slackers, but try to cultivate friendships with people who are as driven as you are, too.     No matter what industry you're in, it's all about who you know. Be friendly with your supervisors – without creeping them out by trying to be actual friends. Go to conferences and lectures and meet as many people in your field as you can. Whenever you do meet someone, have a business card ready to hand over, a firm handshake, and a steady gaze. Flatter people without sucking up. Learn to summarize what you do in a sentence and make an impression so people remember you. Don't feel sleazy about it; it's all part of the game.  You never know who can be helpful to you in the future. Don't embarrass yourself by sucking up to all of your superiors and ignoring anyone who is below you. Getting ahead does not mean starting at the top. It means starting the race in the back, near the nervous, inexperienced runners, and working your way to the front of the line at a steady pace. This means that you will have to prepare to do a lot of work for not a lot of money, at first. Don't think that being a leader, a boss, an executive, etc., is your birthright – it's not. You have to put in your hours, even if you feel like you're too smart for your job or like...

How would you rephrase that briefly using Chinese?
与能让你快乐的人交朋友。 拓展人脉。 肯吃苦。 成为行家。 多与人面对面交谈。 不要为了最终的幸福而牺牲当前所有的快乐。 不要再等待所谓的完美时机。
