Others' plans for you
Don't trust others' plans for you. You'll soon discover they don't have very much planned at all.
I'm not sure where I first heard that advice, but it appears to be derived from a quote which is, accurately or not, attributed to Jim Rohn:
If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much.
I tend to prefer the shorter version, but they both have their strengths. In any case, I think the advice is sound, and I hope to remember it.
