I'm still technically a kid still in school. But why would I want an actual career? Do you think that it is gonna make me happier or more complete as a person? It won't, so there is really no need for me to go that way. You don't have to do things you don't want to, I don't. And it really made me enjoy my life more. For example I don't like cleaning my house. That's fine then I won't do it. -But it is gonna stay dirty that way. Then I will hire someone else to do it instead of me. And meanwhile I will do something that I enjoy such as making art and then I'm gonna sell it to make the money to pay that someone who did the thing I don't like. That's how I live my life. This is correct but I didn't talk about that. What I meant was that there is really no need to find a specific motivation or unmotivation and simply doing what you enjoy is gonna lead you to happiness.I don't know what kind of job you have, but that won't fly in an actual career. You have to do things you don't want to do; that's just part of life.
It's simply impossible not to be motivated. Your body will force you to breathe, drink, eat, and sleep. If you're doing other tasks, you're motivated to do them by some force. That doesn't mean that you're out there writing inspirational thoughts about doing them, but something is causing you to desire to complete that action.
A career in "X" field has a couple things going for it that making (edit: freelance) art, for instance, doesn't: 1) Stability - You can wake up and know that today, you're going to make about "Y" dollars. Tomorrow will probably be the same. 2) Upward mobility - You can reasonably expect pay increases and promotions and you gain proficiency in your field. If not, you can try moving to a different company that values your skill set more. If those things don't matter to you and you think that you have the skills required to stand out as an artist, more power to you. You'll enjoy setting your own hours, not having to deal with shitty office politics, and you can do your work just about anywhere. You might have to clean your own house until you get famous, though. Best of luck to you!
