There are things that you used to handle well, but then time change everything seems so overwhelming and you can't figure out . But the beauty of life is you can always try, and try until you get it right. But just in case you can't , well at least you try .
Anyway, i didn't break my back , i can only hold my self when i am close to the wall or anything that will support me when i fall. I need to be more confident, stronger to do it and lot's of practice.
