I never thought about traveling when I was a college student because I barely made enough to pay for college tuition. Thanks to the government, the college grants helped pay 95% of the tuition. My minimum waged $5.5/hour part time job at Disneyland helped cover the remaining %5 + clothes, gas, oil changes etc. My parents helped provide the shelter.
In the summer between my 3rd and 4th years, when I knew the the school workload would be much less than the previous 3 years, I got a second part time job delivering the newspapers from 2am-6am. I continued to work 2 jobs until a week before the dental school started. I had almost $10k in my saving account, which was almost enough for 4 years of rent (I paid $250/month for sharing an apartment with 4 roommates).
I didn't feel I missed out on anything. I learned a lot from living at home with my parents. My mom taught me how to cook. My dad taught me how to fix things around the house. I didn't take my very first expensive vacation until I was 29 yo.....it was our honeymoon....a memorable 5-day trip to Hawaii.
