Hi Mariana (from Katy, Tx...I'm from Texas as well),
To put it simply, you have to like solving problems. And you have to be curious to ask questions (as you did in this forum). Of course, in our toolbox as engineers is a whole heap of Math so there's no getting around that. Finally, over the years and across many projects, it becomes more and more apparent that you have to have awesome honesty and character as the solutions you put in place will affect others. So study hard, ask questions and take advantage of every STEM opportunity that you can.
I hope this helps you along your journey....thx for you question :)
