Best life changing impetous I received has come not so much from advice as encouragement. When you try something and someone who you respect as an expert in that field tells you "You've got the gift, son," or words to that effect, you just can't help but be motivated. I've had that happen a few times.
It is praise which one senses is genuine that makes all the difference. Certainly such praise brought me to Creative Writing and Public Speaking, two of my passions. Forty-five and forty years ago respectively and I'm still into them.
As for good advice, I'm sure I've received a lot...but I can't recall any that has ever made such a difference to me than 'well placed praise.'
