How did you find the strength and patience to resist this temptation?

Holding isn't just easy, it's a test of your patience and self discipline. Most persons can't hold enough because they lack patience, and often shaking when they see a drop in price this causes them to sell out of fear early.
The only way is not give room for emotions and stick to your plan, regardless of any market situation. This will help and save you alot. The market transfers money from the impatient to patient. Once you build this qualities you will have the inner strength you need to hold in a long run.
Invest, Plan and execute.
