Most employers are not actually all that interested in what _you want_, but in what _you can provide them_. If necessary, they will pay for that. A great many applicants that come by our company have as motivation "to develop myself" and similar. That won't get many employers excited. If you come by and tell us: "I have a great idea to make/save you X euro/month (and are credible)", that would make employers much more likely to hire you.

Imagine if a grocer told you: I want you to buy this cucumber because it would make me feel great about my sales skills. Would you buy the cucumber just to do the grocer a favor? Now compare that to a grocer who tells you: "These cucumbers are delicious, healthy and will make you feel great about yourself for eating healthy food." IMO, the second grocer is much more likely to sell a lot of cucumbers, because he focuses on what his customers want instead of what he himself wants. The same is true for selling your labor.
