<p>I think you should just pick one and stick to it - the two aren’t especially compatible.
Also, in your specific situation, I would not recommend getting another degree. You already said you liked finance - why not just polish your less-proficient finance skills and continue searching for a job? It’s much easier to learn to be personable than it is to spend four more years learning another trade.
The grass really isn’t greener on the other side in this situation. Engineering has its own problems, and while the job market isn’t great, it’s not bad either. </p>
<p>You don’t need another degree. Do yourself a huge favor and get back to job hunting (brush up on the necessary skills as well).</p>
