I know people who are trying to get multiple degrees within four years of undergrad and are taking 7-8 credits when most are only taking 5. I admire them for the hard work they put in, but I feel like some of them are clueless as to why they are doing it, except the fact that they want to just do really well and look good.
I remember in high school I used to do the same. Now I keep on asking myself the same question over and over again. Is this really want I want to do? Things have changed drastically as well for me. Much slower, but more efficiently. Although, I really wish I had more time for my side projects.
And I totally agree - trusting your gut is probably the most important thing you can do. Just be sure to keep it in check from time to time.
