I said small size is pointless… anyone actually felt the compounding snowball for real?

I kept self-deprecating with 'my stack's too small to matter', but seeing people who steadily compounded it up is wild. the snowball idea — reinvest even small gains and it balloons later — has anyone actually felt it? how many years did it take and how did you hold your mindset mid-way? give the small-stack crowd some hope...
