Depends on your definition of successful. Will these advice help make you next tech billionaire. Most probably no, that requires too many dices to land in your favour.

But all of these advice while not novel and may sound superficial, will make you more happier and more successful if followed.

e.g. a ~20%(adjust by country/age) CAGR in income will make most feel monetarily successful no matter what the start point is. Spending less time on TV and more with family/friends will for most give them more happiness. Working hard may not be enough but almost always a pre-requisite.
