I think it's very important to have a plan in our life. I would not say that we need to plan every single move, but at least have a goal and a plan for it.
Know exactly what you want to do in life
I'm sure you know that you want to be successful; even if you don't know exactly what you want to do till you get there. You may want to be a fashion designer with your own fashion show and collection, or an amazing artist with your own gallery, maybe a great writer publishing great books, or even an excellent Chef with your own restaurant. But do you already know what you want to be?
Make a plan
Don't forget to write everything down and start thinking as you already have that business/job. It's a store that you want? Write the name of the place, how many employees you want to collaborate with you, where you want to have the store, how much money you will need, what's gonna be your first collection, how you gonna make the clothes, how it's gonna be the decoration, what events you should do to promote. You can write everything you want.
Now the real stuff
What do you need to start saving money for your project? You also need to think how much time you will need it, what you can do, which jobs you can find. Maybe it's better 2 part time jobs than one full time, you can do some extra jobs as babysitting, cleaning someone cars, taking your neighbor's dogs out, teaching math/english/french or whatever to someone . Think an amount of money that you can do during this jobs.
After all I think you can start doing some progress! I mean, everyone can. It's just a question of focus in what you really want. Trust me, it's not easy, but everyone can if they really want! Just make a plan.
