Depends on the job you are working now and the job you are expecting. Some jobs are harder on you than others, some majors are harder you than others, and then you have to compare numbers.
Lets just throw out some numbers for example. These are typical for college students, and may not apply to you (I saw your post above of $1k but you didn't say if that is per week, per month, or what).
[*]Suppose you make $8/hour at your college job (roughly typical for college students).
[*]Suppose your new job after graduation pays $40k/year (also roughly typical, but varies greatly).
[*]Suppose having full time school/full time college is so stressful that you take 6 years to graduate (also typical for people working full time).
[*]Suppose that if you didn't work while in school you would graduate in 4 years.
Work in school
After 6 years, you would have made $8*40*50*6 = $96k, and you'll have a new $40k/year job.
Don't work in school
After 6 years, you would have made $40k + $41.2k = $81.2k, and you'll have a $42.4k/year job (I assumed a 3%/year raise).
So, by torturing yourself for 6 years and having no social life, you earn $15k more and have a worse job position. Is that worth it? Student loans are wonderful loans. Don't stress over them.
