"Don't always think about earning the last penny. If your goal is $100,000, taking profits at $99,400 doesn't differ much from the final profit; if it goes up later, that's the market afterward.

The key is that you have executed a complete round according to your strategy; the old strategy is finished, and new opportunities will continue to appear. Investing isn't necessarily about suffering first and then enjoying, but starting with enjoyment is always sweet."
