Detach from the things that bother you so much... you nearly slip into your less than your best self. Don't get caught up in the negative. Deep breath. Don't let stuff bother you. Don't let it in. You're happier than you've ever been. Walk away from anything that tries to take that away. Grace and dignity. Maintain that mindset.
You have a busy life, juggling work, home, friendships, relationships, kids, and you're so used to being all things to all people you've forgotten who you really are anymore. Learning about yourself - what you need, want and like, what really makes you tick is the first vital step to increased happiness, reduced stress, contentment and clarity. After all, if you don't know what your needs are, how can they possible be met?
