Fix the bug of giving zero rewards for completing a 2nd Epic Win + keep a history of completed Epic Wins
After I completed my very first Epic Win, I got "Real Life Superhero" achievement and maybe (I didn't check) some resilience score reward.
But after I completed my 2nd Epic Win, there were no rewards.
Given that it's relevantly easy to complete the first epic win while there is novelty about the SuperBetter tool, it seems like a good idea to reward non-first epic wins as well, to encourage users to keep up the good work.
Yes, the rewards are abstract (score, achievement title), but on tough days, in tough life situations, in situations when there is a whole bunch of epic wins to complete before the life situation gets at least a bit better, they light up the mood, give the sense of actual progress.
That's also why it seems like a good idea to show users a history of their completed Epic Wins (with dates of completions) — to provide a clear sense of progress., increase the feeling of self-efficacy.
