Nurture and keep alive all that makes you feel most alive. Maintain an awareness of your passions. Practice them, dream about them, schedule them in with all of your other to-do's. Don't forget your dharma (why you are here, your purpose).
Don't waste time and energy wishing things could have been different. It is this exact path that has made us who we are. These were the lessons that we needed to learn and the compassion that we needed to be able to feel for others who have walked a similar road. Be grateful for all that was, and hopeful for all that is yet to come.
Do not get addicted to your problems, and the crisis that is created from them. Do not attach and make them part of your identity. Your obstacles are here for your personal growth. Use them as stepping stones to the better YOU. Move through it with grace... there is so much light on the other side.
