You may never be too old to give up a dream, but as you age, you have to accept the reality of your situation. I cannot swim. I took lessons several times. My knees are crooked, and the result is a negative kick that sends me to the bottom. I did jump off the high diving board (with life jacket).
I want to be a published author is some national publications. I consider that a possibility and am pursuing that.
There were a lot of things I dreamed about doing when I was younger, but the lack of ability, talent and energy, makes it necessary to focus your dreams on the attainable or at least the near attainable.
