The lesson is, because there will be many lemons in life, to learn to make the proverbial lemonade - and be open and honest. That's the best way of doing damage control and positioning yourself for success.

This quote is telling us that life can sometimes be tough, and there will be times when things don’t work in our favor or don’t go as planned. In these moments, it is important to remain open and honest and to react in the best way possible. This will allow us to limit the amount of damage that might be caused and helps us to put ourselves in a better position to succeed. In other words, when life gives us lemons, we should make lemonade (i.e. find a way to proactively make the best of a difficult situation) instead of dwelling on the negatives.
