There are many things we should be thankful for in life no matter how small they may seem. Sometimes it could be as small as thanking God for being able to eat or sleep, they are equally important as life is. There are people who wish they can sleep, eat, or be in the position you are today but life has denied them that privilege, as long as we breath, make achievement no matter how little it may be, is healthy, and can still love, give thanks. Our heart should be filled with thanksgiving on a daily basis because each moment of our life is a privilege we gain by God's mercies and grace.

Reflect on your life, and count your blessings. Count the things which you have achieved, the favor you've gained, the many things that you've enjoyed, then you'll be amazed what the Lord has done in your life. A cripple wish he can just walk, someone who's walking wish he can own a bicycle, someone who owns a bicycle wish he can own a tricycle, someone with a tricycle wish he can own a car, someone with a car wish he can own an aeroplane, etc. This shows how our needs make us forget the importance of giving thanks, whatever we are today is not by our strength, nor our skill which most people are boastful of, but by divine privilege.
Take a moment from the hours of your day to give thanks for the things you've enjoyed and God would make open other doors that were shut.
