Some of my biggest regrets are doing what I thought was best when I should have done what everyone else was doing. This ranges from from not buying an overpriced house 20 years ago, to not partying at college, to following some interesting but unpopular technology. Its not all bad doing things your own way but you have to be careful about straying too much.
That house is now worth 3 times more today than when I bought it, almost all popular technologies from 10 years ago are dead and unmaintained today whereas the technology I made for myself forms the basis of my software company, and frankly I don't know many people in their 30s who still continue to maintain the same kind of friendship with their party buddies.
All this to say that it's irrelevant whether you do things everyone else does or do things no one else does. It's just a very poor way of reasoning about anything in life.
