tip of the week for newbies 4/18

[Sean Carroll]

Being new and there being so much information I figured I would try to start a weekly thing for all of us newbies called "tip of the week". Hopefully, some of the more experienced investors will overflow this post with tips every week. This can be something you wish you knew or did when you first started or something you just learned or even a trick of the trade you know and love. Thank you to all you share and help!!!

So what would your tip of the week be to any new investors?
