You are a great force today. Use your initiative and drive to make strong progress.
Don't wait for the future; the future is now and you should be working towards your goals in the present if you want them to become a reality tomorrow. Every minute that passes is now relegated to the past where you cannot change it. But, every minute that you live right now can influence the future. Live now, make the most of now, because now is what creates the future.
Mentors are great, but they don't always have the answers that best fit your situation or needs. They won't always be right. Take their advice, but supplement it with other knowledge in order to make the best decision.
