All your strategies related to trading are fine but I want to add that not much greed can be made in trading platform. If you are greedy in trading platform then you will lose the most. Learn to deal with greed. This greed is a very terrible thing. One more thing I want to add here is don't trade with emotion. Trading should be done by understanding the market conditions. Now you have made a profit from trading but later you can lose money if you aim for that profit and trading with passion without understanding the position of the market.
That is what OP means, having patience = less greedy.
It's like the opposite of greedy is patience.
It is really the main enemy of every trader, especially those new ones who just starting. You need to surpass and endure the greediness, you must be able to control it which comes with your psychological.
