You have to study for THAT exam, go to THAT school, study THAT subject, enter THAT company, learn THAT language, marry THAT person, have THAT many children, attend THAT event and so on. How well do you do all those things?
Just because someone else tells you being/doing/having something is a good idea, will it always work out well for you?
Who is the one person who knows what will work for you?
You know if something is working for you. It feels light as a feather. Unlike all the heavy stuff you KNOW doesn't work for you but you do because someone else told you to.
So if you're not as happy as you'd like to be, start listening and trusting YOU more by asking “Does this work for me?”
Notice whether you feel heavy or light, and if you'd like to change the heaviness, ask “What else is possible?”
