1. You can't count on someone else to make you happy.
    I paraphrase slightly I think, but this is the gist. My sister said this when I was heartbroken, over a guy who still breaks my heart from time to time. It seems so obvious, but it resonated so hard, and I go back to it often. Wise sister.
  2. Follow your heart but trust your gut.
    I can't remember who actually said this to me. It's a little confusing but still good advice.
