Limiting the execuses you give yourself

Use your current decade of life to do all of the things you wish you had done two decades ago that would have, had you done them, put you in a better position to be achieving greatness today. And so if you are in your 30s, use 30s to 40s to do the things you wish you had done or known in your teenage years that you think would be helping you right now. This kind of thought experiment and approach limits the number of excuses you can give yourself for not taking action on the good information and wisdom that you have right now.
