Okay, so most of your family and friends trust to be around you and trust you as a person (when speaking the 2nd person perspective I do mean the first person perspective myself as well.). The times you want to ask them for advice is not when they are not working or when they are not busy, but when they give you the time for it. If you ask them one time during the day and demand it again later on, your opportunity will be gone and you will cause conflict. However, if you wait until the person brings it up again or at a time when they are talking to you (MOST IMPORTANTLY WHEN THEY ARE NOT IN A RUSH), then it would be a good time. What I'm writing is about not being intrusive. Seriously, people get tired after a long day. Sometimes we have to risk going with our own advice without approval of others which I already covered in the different posts on social skills.
Better yet live your own life to learn from it.
