Let’s face it, sometimes life feels like it’s falling apart at the seams.(23)Perhaps you’ve lost your job, or your marriage just ended, or you failed to pass an exam and now you are simply feeling helpless and defeated. Winston Churchill once said: "Success consists of going from failure to failure without losing enthusiasm. " Today I want to remind you why, even though you may be feeling a bit like a failure, you are most definitely not. Here are some signs that show you are doing well in life even though you don’t think so!
    No one said life was easy and while the bumps on the road may hurt, the ride is definitely worth it. Think back to your failures and defeats. You must know they were all for a reason and part of a grander plan. Each difficulty has led you where you are at today: each trial has molded you into the magnificent, resilient, person that you are. Continue to move forward in faith, hope and love, knowing that each experience has taught you what you need to become who you were born to be.
    The fact you are feeling a bit down because you haven’t achieved what you want to achieve shows you are trying.(24)In the grand scheme of things, you always strive to be better and for as long as you continue to do that, happiness, success and love will come—just don’t give up. Einstein once said: "It’s not that I am so smart, it’s that I stay with problems longer." Hang in there and never stop striving to be all you can be!
    Whichever way you look at this one, it is still a win-win situation for you. If you have a job: kudos! Keep at it and know that you are richly blessed. If you recently lost your job, don’t fret! You’ve gotten a job before: you can get one all over again. Perhaps this is the opportunity you’ve been waiting for to do something you truly love to do. Keep searching, keep hoping, and know that you can accomplish the seemingly impossible if you work hard and believe you can.
    In this day and age, you can learn anything and everything you want. Knowledge is truly at your fingertips!(25)Since knowledge is power, seize that power and let it assist you in the pursuit of your dreams. Take advantage of all the "learning" opportunities that come your way.
    Hope you enjoy today’s lecture. Thank you!
