I would be happy if I could do even half the things simultaneously, that you have listed out in your post. (Quality time with wife + 3 Kids, Bootstrapped Startup, 3-4 Consulting Projects, Being to the gym 5-6 times a week, 2 podcasts per week, ...)
If we rewind a bit to when you were just starting out after college, were you pretty efficient and disciplined then as well? I am just curious whether self-discipline and efficiency can also be cultivated and improved upon drastically, later in life as well.
Thanks for writing this post. It inspired me to utilize my time more efficiently.
