It occurs to me, perhaps not for the first time, that if you concentrate on 'living your dream' and 'not settling for less' and 'taking that chance' and not 'blooming where you're planted', you're actually losing out on the present by focusing so thoroughly on the future that you miss the entire process of becoming what you already know you are.
You don't need outside validation. You only need to believe in it yourself, whatever 'it' may be.
I have no patience for people who are so focused on the fact that they are not living their dreams that they lose their present. Bloom where you are planted is not settling for less. It's making do with what you have, and realizing that some dreams are realistically unreachable; that some dreams are just that--dreams, and should remain that way.
If you have a passion, that's great. I have one, and let me tell you, I wouldn't trade it for anything in the world. But if you spend all of your time on the coattails of those you feel are living the life you hope/wish/dream you have, you're missing out on the fact that their life is NOT your life. YOUR life is your life. And it's totally different from anyone else's life, and totally, uniquely yours.
There's nothing wrong with working a job that pays well enough to cover your living expenses, bills and rent or mortgage with some leftover for savings, hobbies, and whatever else might interest you while you pursue your passions on the side. Hundreds of thousands of people throughout history have done such things. There's no shame in it. Anyone who says otherwise is probably selling something to help you 'live your dreams'--the ultimate pyramid scheme, because of course, with no market for what they're selling, they wouldn't be able to live their dream to begin with.
What do you want? What do you want your life to look like in two years; in three; in five? What are your dreams? Are they your own dreams, or did you borrow them from someone else?
What is your passion?
