Instead of being blind to opportunity, it's best to stay optimistic and open. It's easier to see them with a positive attitude. We can look around us and see all the opportunities that are presented to us daily in the crazy thing we called life. Some are apparent, some take work, and some are found in the rubble of a hardship.
For the ones that are apparent, seize them. It's rare that they are handed to you. For the ones that take work, work. It will make you appreciate them that much more. For the ones that are found in the rubble, stay strong and look for something to take away from it. We learn the most from life's hard lessons. At least, that's what I have come to find.
These opportunities could be in the form of relationships, friendships, career paths, making amends, taking control of your health, volunteer work, challenges, new experiences, doing something kind. Remember, there are opportunities everywhere. It's up to you to see them and take advantage of them. Your life will be much more fulfilling.
