New changes will bring joy into your life. Be open to them. Don't close the door to your own happiness.
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.
Don't react angrily or wearily to negative feedback; reflect upon it and be honest about whether or not it has some merit.
