A positive attitude is something everyone can work on, and everyone can learn how to employ it.
Holding on to anger, resentment and hurt only gives you tense muscles, a headache and a sore jaw from clenching your teeth. Forgiveness gives you back the laughter and the lightness in your life.
A fulfilling life is different to each person.
You have to acknowledge your dreams, and not just wait for life to happen, and opportunities to come knocking at your door.
