I read recently that there is no perfect investment, strategy, or plan. It's also expressed here:

Back to our usual topic of investing. You can go crazy in trying to figure out what will work the best “in this environment” or you can just go indexing and own the entire market. Indexing is not going to be the best. You can stress about whether to go with small cap and value tilts, the newfangled quality and momentum factors, or plain vanilla indexing, or the choices among target date funds, lazy portfolios, Vanguard PAS, Fidelity Go, Schwab Intelligent something, Betterment or Wealthfront or you can just pick one that you can stick to and move on. Whatever you choose, it’s not going to be the best.
