Could it all be due to problems at the 30,000ft+ level? If you're not sure about what you want to acheive in your life, or what your life purpose is then any big acheivement is likely to leave you "trapped by success". If you end up making $millions with a great business plan but what you actually wanted to do was live simply and enjoy nature, how difficult would it be to give up the $millions (or even have the time to stop to realise it's not what you really want)? Add to this all the external messages (media, family, society, government, peers) which relentlessly tell us what we should think we want. It's no surprise, to me anyway, that so many people feel so demotivated and can't understand why.
