Unless! You are reading this from the afterlife that is.
I remember my Grandmom at age 81, saying to me, “I don't feel any difference in the way I think or feel in my mind then when I was 18. That darn mirror is lying to me again.” She lived to be 94.
Her point that day was in response to my complaining about time passing me by and I seemed to be standing still or falling behind. Everything I saw in my life seemed like failure. Little did I know then that none of my failures were as I perceived them. They were training for the future, full of education that would make me successful down the road.
It took 49 years for me to stand up and take responsibility for myself because I had nothing else I could do; I was broken, broke, and homeless. I picked myself up and started moving forward and refused to look back.
I went back to college and graduated Cum Laude; BFA in Studio Art, at age 55. Started a new job, at age 63, as manager of a small restaurant/bookstore/B&B, and office manager of the small publishing company, all owned by a couple of over achievers like myself. I bought my first home at age 64, remodeling almost done, with studio space included. I come home and make whatever Art I feel like, and am taking marketing lessons on how to succeed as an artist, just for me.
Yes, there has been a lot of just plain shit that occurred during all this time, but also some incredible miracles. That is another much longer story.
If you want it, go get it. If you don't go get it, don't blame anyone but yourself. You may for unforeseen reasons such as health, family crisis, etc. have to amend how or when you build your dream. But let no one steal it.
