Think of patience as a primary part of your trading strategy. Don't assign it a secondary or lesser role, elevate it on the list of what you consider important. And don't be put off by it when it doesn't seem to be working — it's working.
Don't start feeling self-righteous about not trading, as if now it owes you (because you have been so disciplined and patient). This is a trap. Don't start to feel like a martyr from it. Such a feeling may seem innocent, but then you are only one step away from losing patience and putting on a trade.
