A lesson I learned in childhood:
Never stop learning, even though there is no way any single person can know everything, never stop educating yourself and asking questions.
When people ask me for advice:
I let them know what I would do if it were me and why. If they’re asking, they are looking for an opinion but I always make it known that at the end of the day, their decision is their own and any advice I give is just an example of how I’d handle a situation but in most cases there is no “correct” answer or way of doing things.
