i've learned the hard way that people come and go in your life, its up to you to keep them in your life but they wont always be around.
you cant rely on other people all the time to hold you up or carry you through life, sometimes you have to walk on your own two feet and make your own mistakes
its nice to have someone there to guide you but if you don't make your own mistakes you cant learn from them.
also, just because people make certain choices, it doesn't mean that choice is right for you. if a person doesn't enjoy something, or something doesn't feel right for them, never for one minute think that its that way with you, each person has their own needs that they need to fill themselves. decide what YOU want to  do instead of following in the shadows of those around you.
im not saying you cant gain anything from the advice of others, but if you become attached to that one person and find your living off their dreams and goals, what happens when that person leaves? where does that leave you?
it always makes you a better person to be strong and stick through things in times where you feel like giving up or you feel like its not going to work. don't give up on something that could be the best thing thats ever happened to you.
basically, be your own person, don't be a shadow of someone else's.
