Instead of starting with someone else’s “how,” begin with your own “why.”
That is, define the reasons why you do what you do before you listen to anyone’s opinion on how you should do what you do.
Your goals, your priorities, your definition of success, and your concept of happiness sets the context for what is and isn’t relevant to your life.
Everything is wrong and everything is right depending on the context and the individual.
Nothing is absolute in the realm of advice.
There is no path to personal development that will yield successful results without a vigilante commitment to 1) thinking for yourself 2) weighing everything you learn against your own subjective convictions and experiences 3) experimenting with different approaches even after you’ve had several failures and 4) taking personal responsibility for the outcomes you create through your choices.
If you’re looking for a fool-proof approach to self-help, there isn’t one. Every good piece of advice that has ever been given is fully capable of making your life worse if you aren’t careful, conscious, and creative in your personal application of it.
