I don't know if there are any lessons--if there were I would be happy to share them, but I am still figuring it all out myself. I managed to squeeze out a few bucks. I know that's just the way it is some months--you are up and then it goes flat on you. Maybe I am just being a big baby, whining at everyone here, but thanks for commiserating. Portugal messed me up. Lucky for them I love their beautiful country.
Shorts is telling me to take profit earlier (and needless to say, I wish I had in this case) but taking profit too early is actually one of my problems. So now I am trying to learn to stay in things a little longer.
What I am doing is experimenting with short straddles on ETFs and ETNs, trying to find the optimal time to take them off and put them on. For example, put on 2-mo positions on a high volatility day for that underlying, adjust as needed, then take them off a month later (a month prior to expiration). This time I decided to wait a day or two longer, and it did not turn out to be a good thing. However, I think it will take many more of these trades for me to figure out the general course of things and develop a mature game plan. I have only been at them for about five months.
As for the flies, those are a little more comfortable for me because I have more experience with them. Those positions are still on (so maybe it's bad luck to talk about them

--one can be a little more relaxed with those. I could have taken them off early at 11-12% instead of trying to get 13%-15%, but again I am trying to be just slightly more aggressive. I may still get 13-15%, I don't know. I start at around 30-45 days and get out at around 18-25 days to expiration. They are wide flies so they act a lot like straddles. Wait for high IV days, put one on, then let the market move a little, wait for another high IV day, put another one on, etc. Adjust when necessary.
I like the ITM bull spreads when the market is acting like this--reasonable upward progress with helpful pullbacks that allow you to put positions on. Even though the skew is generally against you it is still possible to make money. I like the blue chips for those because they are liquid, and the blue chips are just starting to run now. But I don't do too many of these directional things.
No lessons here, just a lot of rambling....
