First am happy that you have impacted so many lives by mentoring them on the things that will be useful for them. Seriously, my past year and the year that is about to end has been full of up and down. But at the same time, I have achieved so many things while make some mistakes. Well, will write more about that
I think ups and downs are acceptable if one is moving in generally the right direction. Life isn't always easy, or agreeable, but it is all we have and we need to keep taking steps, keep moving.
