Personal achievement is sometimes more a matter of saying "NO!!!" than YES, depending on your background and circumstances.
They used to call it "putting your foot down". Actually, it's learning to say YES! ONLY to That Which Gets You Closer to Your Goals...more often manifest as blocking off any distractions! Develop what Galt-in-Da-Box calls "The habit of NO!!!" in dealing with:
-Your own doubts, fears & worries.
-Acquaintances with poor attitudes.
-Scandlous skanks who want to use "love" as an excuse to move in & leach off of you.
-Alleged "friends" that are actually looters & moochers.
-Any interaction where you are associated with any kind of perennial loser, gimme &/ freeloader.
-MLM scam pushers - especially if they are relatives, friends & associates.
-Any other kind of "demotivator".
Winning at anything requires goals & planning, but it also involves sacrifice. No one can have anything for which they are not prepared to pay a price. If you are in a toxic relationship, or a family situation where alcohol, substance or personal abuse are commonplace, you must do whatever it takes to remove yourself from it, and seal yourself off from the networks of negativity & manipulation involved therein.
Most animals, when trapped, will do anything - up to and including gnawing off a limb - to get free...Human beings are the only animals dumb enough to want to make the trap livable!
