One of my favorite proverb is "When the water rises, hurry to collect some." It's often said when the opportunity came to life. Hurry to harvest it before that chance to slip way. It means that when there is a good chance that came through to take the opportunity and benefits fully. Before this great time period elapsed. A similar proverb in English is"Make hay while the sun shines." I like it because it can make my decision easier. To get a chance to came to life without hesitation.
