Welcome back scintillady
Trying harder is a good principle to go by, but do give some thought to what you're actually trying harder at.
Trying at harder at strategies that have let you down in the past is really not something you want to devote energy to again.
Think about things you haven;t tried, or different approaches. Really give it all you've got, and I'm sure you can wrest a different outcome from all hard work
any ideas on what you might do differently this time?
