For me the main lesson, is tha everything is possible. If we get in trouble, there is always something that will help. Do you remember the situation in a chess game, when you don't know which move the next have to be, and you are loosing.. You spend some time to think about the moves and after find some move that will change the game in your way.
Conclusion is that never give up and don't live in a bad mood, as we always have some move or something close to us but we just don't see that, that will help us.
We just have to be with an open mind.
I learned from Bitcoin is like digitally paying in cash, in that you can move money online from one person to another person without using an intermediary like a bank, a credit agency, a Paypal, or a Western Union, and you can do so without attaching your identity to the payment. Its like having your own email server and creating a different address for every message you send out.
