Do dream jobs still exist?

I’ve been thinking about this recently while on my job hunt. Remember when you were a kid and asked what you wanted to be when you grew up and you were told to dream big?

I wonder now if what was originally seen as a question to help broaden our horizons as kids, as adults just work to set unrealistic expectations on our lives, and places pressure on us to define ourselves through these unrealistic career goals. Which leaves little space to define ourselves by other interests, and who we are as people and what our purpose is.

Does chasing a ‘dream’ career in an industry suppress other sides of our personality and diminish other interests? When I was studying I was known as the ‘sports girl’, because everyone assumed I would chase that interest it felt like I wasn’t given any space to explore my other interests.

Rainesford Stauffer wrote for Teen Vogue “As work dominates more of our waking hours, it also monopolizes more of our identities, meaning career transitions, job losses, or financial strains often double as identity crises”.

There have been times in the last few years that I have felt so unlike myself. A few years ago, I thought I knew exactly where I wanted to go and what I wanted to do, but linking my identity and self-worth into this supposed ‘dream job’ just made me feel like shit, and when none of that has happened, it makes me feel like a failure. When in reality, I haven’t failed, I just changed my mind, and decided what I thought I wanted, I actually didn’t.

Dream jobs can change based on so many things, but why do we have to have an endgame in our careers at all. Can’t we just enjoy the journey? Of creating a career where we can grow and are given room to grow and better our skills and expertise. Can we have a dream job right now, a job that embraces our current interests and current purpose while allowing us to grow as a person while also increasing our skillset.
