You could die of thirst even though you are surrounded by water if you don't take a drink
Your glass may only be half full but it will quench your thirst if you take a drink.
You may not have everything you ever wanted but as long as you have everything that you need you should be grateful.
If you expect things to go perfectly as you had planned then you better plan on being dissappointed because nothing is perfect.
You can't wait on the perfect opportunity because it doesn't exist and you will miss the opportunities that come your way.
Your dreams can't come true if you don't have dreams. Keep your dreams realistic or you will set yourself up for failure.
Remember you can't please everyone so don't try. But at the end of the day as long as you are proud of everything you have done that is all that matters.
