Change also doesn't come easy. Sometimes it happens overnight, (like a thief taking away in one fell swoop what you took years to build) and other times it's slow and painful.
When it's personal change, then it's an on-going struggle really, because deep down we know what needs attention within ourselves - be it medical, physical, financial, emotional or spiritual. We know but we don't always accept the truth.
Our old ways want to trick us into thinking that there's nothing wrong with us. But if we are on a path to continuous self improvement, we must be willing to face the music and be truthful with ourselves.
Truth hurts. It does. The truth about ourselves isn't always pretty, but then again life isn't always a bed of roses either, it's a continuous cycle of build, destroy and rebuild again.
The purpose of all of this is not to accumulate massive structures within our lives, but to enjoy the journey and be willing to improve ourselves so we can be the best for ourselves and other people.
Positive change is the hardest thing to do, I think.
