No, not really. When I was young, I sketched out a wildly optimistic plan, where I would contribute $2000 to an IRA annually, and I would double my money every five years. For example, if I started with 10k, 5 years later I should have 30k (10k doubled, plus 2k times 5). Like I said, wildly optimistic. But it was the 90s. In 10 years, that would be 70k. In 15, 150k. in 20, it should be 310k. In 25, 630K, etc. I figured out pretty quick that the magic happens when you get to a pretty big number, then double it, then double that. So I stuck to my plan. It would have taken me a little longer than 5 years to reach each one of my 5 year goals if I hadn't been able to boost my contributions well above $2k per year. But by investing more along the way, I've actually been able to hit the target amounts that I sketched out on the back of an envelope decades ago. Not really a surprise -- just some planning, persistence, and prudent investing.
