"What trapped us is never our age, but our attitude towards age."
Powerful words there you used. It is so true. I said earlier in some other comment I once stood in front of a wall of whisky looking at some of the more expensive ones. I hesitated in spending the money (I don't have endless wealth I can spend on whisky). The thought dawned upon me, I can die tomorrow and then I would have never tasted the whisky.
Whisky is a stupid example, but I think it resonates with your post: it is never too late to start, but you have to start. The first move is the hardest, but once it is done, all will be better. A thousand page novel starts with one word.
Thank you for sharing! Never wait until it is too late. Start today.
