Great post and don't get too hung up about doing the work in your 40's. So many great people have been working on their goals and personal development for a lifetime and if you've read think and grow rich there is some talk about people not getting any great break throughs until they are in to thier 40's or 50's. Some even much later in life. @russellstockley posted a great vlog about persistence. Ok it was regarding his struggle with uploading a video but in life in general it's always persistence which overcomes resistance.
