I am not a proponent that everyone should be an entrepreneur. There are some, including myself, that need the security of working for someone else that fuels our drive and confidence in achieving knowing at the end of the day I will get paid. That said, I also believe in giving everything a try. If you have an idea to be a writer, or business owner, public speaker, consultant then I say why not! Start out as a side business and see where it takes you.
If you have a dream of doing something but your adult responsibilities prevent you from quitting your job and going for it, then trying it on the side is probably for you. Any idea you have can be tried while keeping your full time job. Sure, it may take time and you will be tired, especially in the beginning, fitting it all in but you're tired from binge watching the Real Housewives, Game of Thrones and even NCAA tournament. This time you'll be tired from something that truly makes you feel good.
Carrie Green, She Means Business, has a no non-sense book all about turning your dreams into a business. It's great for people who need a blue print. So, sit down, think about it and do some research then throw it out there and see what sticks. You may just surprise yourself.
