1. Be yourself, because nobody knows you better than you, so only you can maximize your potential and have at it 🙂
2. Listen to yourself whenever you think you should, this may become a little selfish at times, but who cares, we live in a dog-eat-dog world 😛
3. Don’t give up, always remember it will be worth it in the end 🙂
4. And last but not the least, do what you love.
All these advices may come on seeming a little selfish at times but you should know that you should respect people including yourself because you matter too 🙂
