Best thing I've ever done as far as college is concerned is
1. Did well in high school to qualify for merit scholarships
2. Chose a top 10 college for my field
3. Get a job starting at >100k per year
Graduated with debt paid off in less than a year
(this is comment is intentionally snarky to point out that "I did X and this is how I avoided loans" stories are usually unique to a person and circumstance, and ignores the very real problem that student loans are opaque, confusing, and intentionally manipulative for young borrowers, which was the point of this article.)
