We tend to get caught up in everyday stresses quite easily. When we don't get the job we really wanted, we might tend to be depressed about it and loose motivation. When our significant other breaks up with us, we will wallow in our self pity for how ever long it takes us to get over them. Sometimes all these little dramas accumulate and then we loose sight of what really mattered in the first place. That black little cloud will follow you around everywhere and you will be under the impression that it will be there forever.
Shake yourself out of that funk. You are allowed to mourn whatever lose or failure for however long you need to. At a certain point, you are going to have to realize that not everything is eternally bad. Every time something bad happens, it won't last forever. You heal after you are hurt. The sun rises after every nightfall. Nothing lasts forever. Not the good or the bad.
Breath and be thankful every morning for the opportunities presented in front of you. Be thankful for the air that fills your lungs. Find something to be thankful of everyday.
Thank-you, Thank-you, Thank-you
