I came across this useful mental model in terms of picking projects to work on a couple of days ago. I've found this quite useful. The basic thesis being that some ideas/problems are better worked on by people with experience and some by people with enthusiasm. This also fits in some sense with the broader Toy Theory.

There are certain spaces where the only way to make progress is to exercise enthusiasm. These spaces are uncertain, evolving, new and usecases vary. People who operate primarily with experience (>35) are not good with dealing in such environments. Facebook would have only happened by a 19 year old because of the nature of the product. People with experience are better suited to solve for sectors which require their experience. Okta wouldn't have been founded by anybody who didn't have first-hand experience of the problem.

The case usually is never monolithic. People have both experience and enthusiasm. However the ratio constantly changes. This's usually very contextual but there are a few broader trends. Early on in your career, the ratio of enthusiasm : experience is probably 4:1. You can and should taken on problems that are at the cutting edge of the field you're in. As you learn and grow, maybe it changes to 2:2. You can take on the bigger ideas much better because you know the basics well. This may not be the case if you're Elon Musk and decide to launch a space company at 31 with incredible enthusiasm(5:0).

All this is meant for is assessing yourself and the work you do. Don't worry about solving corporate business challanges when you're ripe and 19, you'll get the chance to do so later. Similarly, at 38, don't try to impose conventions on the new breed of talent.

Work on things that align with your forte and you should be good.
