1) Righteous does not mean perfection. Brother Wilks pointed out that while we have been commanded by Christ to be perfect (Matthew 5:48) we cannot obtain perfection in this life, thus making perfection the enemy of righteousness. So rather than strive for complete perfection, strive to be righteous.
2) Keep trying always. Don't give up, as you continue to try your attitude will change making things easier and worth it in the end. Life isn't always about overcoming challenges, but getting up again when knocked down.
3) Keep your eyes on God. He's always there, it's our job to look.
4) Heavenly Father's approval is the only approval that matters. Why are people always focused on what other's think? My nutrition teacher furthered this idea when he shared John 8:29.
5) Look for and remember Joy in your life. Take time each day and think "have I seen the hand of the God in my life today?" When you think back over the day, you're realize things that you never would of, and you understanding and appreciation of little miracles, coincidences and other daily incidents will increase.
I challenge you to think about you life and about how positive you are in life. Elbert Hubbard was wise when he stated "do not take life too seriously. You will never get out of it alive." Enjoy life by being positive, it's much more fun that way.
Other past devotionals have been thought provoking too. I really enjoyed Sister Samuelson's a couple weeks ago (read it here) or Elder Snow's (here). If you ever want to read or listen to the devotionals you can look them up at BYU speeches, though they take a couple weeks before the text is up. You can also watch them live at BYU TV. Every week at 11, take a break and be enlightened. It makes your week better.
And on a side note...
