Congratulations! You're the eternal optimist, a regular "Sunshine Day" of a person.
When it rains, you think about how good the water is for the flowers and trees rather than how wet you're getting.
More likely to trust someone than not, you always see the good in people. Sure, that opens you up for a few let-downs, but that's okay — your great attitude will help you deal with them if and when they come.
In the long run, it doesn't really matter at all; everything's going to be all right! You like meeting new people and thoroughly enjoy their companionship.
In a nutshell, you just don't dwell on small failures — you learn from your mistakes and do your best to make everyone around you happy to be alive.
Keep it up!
