Well yeah of course this is one way of thinking, in that if you could use the early times to do something else meaningful then why not, instead of wasting all of the time on that one single thing which might not be improved that much by all the additional time. That's true to an extent. A good example I can think of is the exam preparation for university entrance exams in China. It's a common practice by high schools to dedicate all three years to it at the expense of other useful developmental activities for students, which is an absolute waste. Just at most one year is totally enough, as proven by some alternative high schools. However, I'd still argue that the problem of most people/individuals (especially as contrasted to huge organizations with loads of formal methodologies) is still delaying/procrastinating too much instead of too little. Too much pressure sucks, so is a rushed product/result compared with a carefully prepared one. So no, unless you really know very clearly what you're doing and how your plan will work out, which 99% of people have no clue about, start as early as possible, much earlier than your estimate, otherwise you'll definitely regret it. Though I acknowledge that this guy mostly talks about management methods, not productivity for individual endeavors.
